What planets are visible tonight? (September 16–30, 2026)
From September 16 to 30, 2026, Venus is the brightest evening planet, with the best views from the tropics and Southern Hemisphere. Look west after sunset for a brilliant point of light. At mid and high northern latitudes, Venus stays very low in twilight and becomes increasingly difficult to see as the month ends.
The night and predawn skies are more crowded. Saturn is the easiest planet to see at night, while Mars and Jupiter are clearly visible before sunrise from northern latitudes and locations just south of the equator. Uranus and Neptune are also high in the night sky, but you’ll need binoculars or a telescope to see them.
Mercury becomes better placed in the evening sky during the period, especially in the Southern Hemisphere. It remains difficult to see, or practically invisible, from much of the Northern Hemisphere.
For the most accurate result, check your local sky in Star Walk 2: planet visibility depends on your location, horizon, and weather conditions.

Quick regional notes
-
Northern Europe: Venus and Mercury are generally not visible. Saturn is the best planet to observe at night; Mars and Jupiter are easy morning targets.
-
Southern Hemisphere: Venus remains prominent after sunset, although it sinks lower as September ends. Mercury becomes easier to see toward the end of the month. Saturn is an excellent target for most of the night. Mars and Jupiter are lower in the morning, especially at far-southern latitudes.
-
Tropics: Venus is easy to spot after sunset, particularly closer to the equator and farther south, with Mercury lower in the same part of the sky. Saturn is visible for most of the night. Mars and Jupiter are morning targets.
Planets visible tonight from the US
Across the contiguous US, Saturn is the easiest planet to spot at night from September 16 to 30. It rises in the evening and remains visible until dawn. Before sunrise, Mars and Jupiter are easy naked-eye targets; Uranus and Neptune require binoculars or a telescope.
Venus is visible after sunset from the southern half of the contiguous US, but it stays low in bright twilight and becomes harder to catch as the month ends. Cities such as Miami, Houston, Phoenix, and Los Angeles get a better view than New York or Seattle.
Mercury is an even tougher evening target. Toward the end of the period, observers in the southern US may glimpse it just above the western horizon shortly after sunset; from northern states, it is generally impractical.
Best planet-watching dates: September 16–30, 2026
September 17–19: Mars passes close to Pollux, the brightest star in Gemini. Look before dawn to compare the planet’s reddish color with the star’s yellow-orange light. Both are visible to the naked eye.
Around September 22: Venus shines near its brightest for this evening apparition, at about magnitude –4.8. Look west shortly after sunset. The best views are from the tropics and Southern Hemisphere; at high and mid-northern latitudes, it’s not visible or extremely low above the horizon.
September 25–26: Mars, Pollux, and Castor form an almost straight line in the predawn sky, with Pollux in the middle. The pattern spans about 12° and is visible without optical aid.
September 26: Mercury passes very close to Spica. Look low in the west during evening twilight, especially from equatorial and Southern Hemisphere locations. Spica is fainter than Mercury and harder to pick out in the twilight.
September 26: Neptune reaches opposition in Pisces and is above the horizon for almost the entire night. However, the nearby Full Moon will make this faint planet harder to observe. Try earlier in the period after moonset for a darker view.
September 26–27: The Full Moon appears near Saturn. Look east in the evening, then follow the pair as it climbs higher. Saturn remains easy to see with the naked eye despite the moonlight. The closest approach falls on September 27 in GMT; your best local view may be on the evening before or after.
Evening planets: Venus and Mercury
Venus: the brightest evening planet
From September 16 to 30, 2026, Venus remains very low for observers at high and mid-northern latitudes and may set before the sky becomes dark. It is much better placed in the tropics and Southern Hemisphere, but sinks lower after sunset as September ends.
Venus remains the brightest evening planet (in locations where it’s visible). Look west shortly after sunset. If you see a brilliant point of light close to the western horizon, it is almost certainly Venus.
The planet shines near its peak brightness for this evening apparition, at about magnitude –4.8. Through a telescope, its crescent grows thinner as the period progresses, while its apparent size increases.
Mercury: a difficult evening target
Mercury is in the evening sky during the second half of September and moves farther from the Sun as the period progresses. Its visibility improves most in the Southern Hemisphere, where it climbs noticeably higher in the twilight by the end of the month.
Look above the western horizon shortly after sunset, with the best chances toward September 30. From northern mid-latitudes, Mercury remains very low and difficult or impossible to see. On September 26, it passes less than 1° from Spica; equatorial and southern observers get the best chance to see both objects together.
Night planets: Saturn, Uranus, and Neptune
Saturn: visible from evening until dawn
Saturn is one of the easiest planets to see in the second half of September 2026. It rises above the eastern horizon in the evening and remains visible until dawn, rising earlier each day as it approaches opposition on October 4.
To catch it near its highest point, look around midnight or in the early hours afterward, toward the southern sky from mid-northern latitudes or the northern sky from mid-southern latitudes. It shines at about magnitude 0.4–0.3 and looks like a yellowish dot.
On the night of September 26–27, the Full Moon appears nearby. Saturn is bright enough to stand out despite the lunar glare, making it an easy target for observing.
Uranus: a late-night target for binoculars
Uranus is visible from late evening or after midnight (depending on latitude) until dawn, but you’ll need binoculars or a telescope to see it reliably. It shines at about magnitude 5.7 and looks like a faint point of light; a telescope can reveal its small blue-green disk.
Uranus reaches a good altitude before dawn across most northern and tropical locations. It lies in Taurus, roughly halfway between Aldebaran and the Pleiades, about 7° from each. These bright landmarks can help you find the right area, but use Star Walk 2 to identify the planet’s exact position. Earlier in the period, look after moonset; the bright Moon returns to this part of the sky around September 30 and makes Uranus harder to spot.
Neptune: optical aid required
Neptune rises around sunset in Pisces and remains visible for most of the night. At magnitude 7.8, it is too faint to see with the naked eye. A telescope at moderate magnification is needed to show its tiny bluish disk; a stargazing app will help you locate the planet.
Brighter Saturn can guide you to the right part of the sky: the two planets appear slightly less than a fist-width apart, with your fist held at arm’s length. Neptune reaches opposition on September 26, when it is highest around the middle of the night. However, the nearby Full Moon will interfere with observations. For a darker sky, try September 16–20 after the Moon has set, while Neptune is still well above the horizon.
Morning planets: Mars and Jupiter
Mars: visible before dawn
Mars is visible before sunrise, shining at about magnitude 1.2–1.1. Its reddish color helps it stand out, although Mars is dimmer than Jupiter and Venus.
On September 17–19, Mars passes near Pollux, and on September 25–26, it forms an almost straight line with Pollux and Castor. Look toward the eastern sky before dawn. Mars is well placed from northern and tropical locations but remains much lower in the sky from far-southern latitudes.
Jupiter: an increasingly prominent morning planet
Jupiter is an easy morning target during the second half of September. It shines at about magnitude –1.8 and rises earlier each day. Look above the eastern horizon before sunrise.
The planet is best placed from the Northern Hemisphere and the tropics. It remains lower from mid-southern latitudes, although its morning visibility improves during the period. Farther south, a clear horizon is particularly important. A pair of binoculars or a small telescope can reveal Jupiter’s four largest moons.
What is the bright star in the west after sunset?
The bright “star” in the west after sunset is most likely Venus — assuming it rises high enough above your horizon. It is by far the brightest evening planet during the second half of September 2026. Mercury is much fainter and remains difficult to see from northern latitudes. Farther north, Venus may already have set by the time the sky darkens.
What is the bright dot before sunrise?
The brightest planet before sunrise is Jupiter above the eastern horizon. Reddish Mars lies farther along the same broad arc, while Saturn is farther west and remains visible from the evening through dawn.
How to find and identify planets in the sky
Most novice astronomers believe that astronomy is an expensive hobby requiring a fancy telescope. But the irony is that beginner-level astronomy is not only inexpensive but actually free.
Five planets — Mercury, Venus, Mars, Jupiter, and Saturn — can be seen with the naked eye, often even from a city. Equipment only deepens your experience; it’s not required to recognize the dots in the sky. In the next few minutes, you’ll learn exactly how to find Solar System planets tonight.
Look for bright dots
Venus and Jupiter are usually the brightest dots in the sky, easily visible to the naked eye; Mars sometimes outshines stars, too. Bright planets may even look larger than stars because their intense light creates a noticeable glow. So, if you see an exceptionally bright dot in the sky, there’s a good chance it’s a planet.
Astronomers use a magnitude scale to measure an object’s apparent brightness. On this scale, brighter objects have lower or even negative numbers. For example:
- Sun: about mag –26.7
- Full Moon: about mag –12.7
- Sirius: mag –1.46 (the brightest star in the night sky)
Unlike stars, the brightness of planets changes depending on their position relative to Earth and the Sun. Here are the magnitude ranges for the Solar System planets:
- Venus: from mag –4.9 to –3.0
- Jupiter: from mag –2.9 to –1.7
- Mars: from mag –2.9 to 1.9
- Mercury: from mag –2.5 to 7.2
- Saturn: from mag –0.5 to 1.2
- Uranus: from mag 5.4 to 6.0 (usually requires binoculars)
- Neptune: from mag 7.7 to 8.0 (requires binoculars or telescope)
Check if it twinkles
Stars usually twinkle, while planets shine more steadily. This happens because stars are way more distant and therefore appear as point-like sources of light. Moving pockets of air in Earth’s atmosphere continually bend their light, causing rapid changes in apparent brightness, color, and position. Planets are much closer and therefore appear as tiny disks, so these atmospheric distortions tend to average out and their light usually looks steadier.
But twinkling is only a clue — not a 100% reliable test. A planet can twinkle noticeably when it is low above the horizon, where its light travels through more atmosphere, or when the air is especially turbulent. A star high in the sky may appear relatively steady.
For the full explanation of why stars twinkle, see our detailed article.
Look for planets near the Moon
One of the easiest ways to locate a planet is to use a bright guide that everyone can easily find in the sky — the Moon. Each month, our natural satellite passes close to planets in the sky — astronomers call this a close approach. So, a bright, not twinkling “star” near the Moon is most likely a planet!
To find out when a planet will next pass near the Moon, check our regularly updated article.
Aim for planetary pairings or planetary alignments
From time to time, planets appear very close together in the sky. A bright planet can become your guide to a fainter one, like when Venus passes close to Uranus. But when both planets are bright, it becomes a spectacular sight to the naked eye.
Even more striking are planetary alignments, which happen when three or more planets gather on one side of the Sun in the sky. They may span a broad arc rather than cluster tightly, but alignments still offer a good opportunity to find several planets in one observing session.
The next planetary alignment will take place around November 14, 2026. Before sunrise, Mercury, Venus, Mars, and Jupiter will gather in the sky.

To find planets, look along the Sun’s path
Mercury and Venus always stay relatively close to the Sun in the sky, so you’ll usually find them near the horizon around sunrise or sunset.
Moreover, all the planets stay close to the ecliptic — the Sun’s apparent yearly path across the background stars. Determining the ecliptic in the sky correctly is difficult, especially for a novice stargazer. You can see it in most astronomy apps or a software program. It is drawn as an arc across the sky.
Planets are “wanderers”
Another way to confirm whether you are looking at a planet or a star is to observe its position over several successive nights. You’ll see how the positions of the planets change relative to the backdrop of the fixed stars from night to night.
Use an interactive star map
After you’ve practiced spotting planets on your own, an app can confirm your finds. The free Star Walk 2 app features a Planet Walk mode that highlights every planet and makes it easier to distinguish them from stars. Simply open the Menu, choose Planets, then tap Planet Walk. You’ll get a live map with every planet highlighted, plus a bottom panel that lets you jump straight to each planet.
If you’d like alternatives, try Night Sky, SkySafari, or Stellarium. Some apps are entirely free; others require payment upfront, and many offer extra features via in-app purchases. For a quick comparison of what each app offers at no charge, see our article about Top Astronomy Apps 2026.
Planet-by-planet observing tips
Mercury: the elusive planet
Mercury is an inner planet that orbits closer to the Sun than Earth. This means that in our sky, this planet is never far from the Sun; the maximum distance between them ranges from 18° to 28°. In astronomy, this is called a greatest elongation, and it’s often the best time for viewing inner planets. Counting both eastern and western elongations, Mercury reaches greatest elongation six or seven times per year.
To find Mercury, look low on the western horizon just after sunset or low in the east just before sunrise. To find out whether it is currently a morning object, an evening object, or not visible at all, check the free Star Walk 2 app that shows the daily visibility of the planet.
A small telescope will reveal Mercury’s tiny disk and its phases — just be sure the Sun has fully set before aiming your optics. Never point an unprotected telescope, camera, or binoculars at the Sun because it can cause instant, permanent blindness and/or damage your equipment.
Mercury is often overlooked, but it’s one of the most surprising planets in the Solar System. Take the quiz and see how much you really know about this mysterious small planet!
Venus: the evening and morning star
Venus is the brightest planet you can see with the naked eye. Blanketed by highly reflective clouds, Venus appears exceptionally bright in our sky, visible even in daytime around its peak brightness.
By the way, like the Moon, Venus goes through phases and reaches peak brightness while appearing as a crescent. As Venus approaches Earth, its apparent size increases, but the illuminated portion of its disk becomes smaller. The balance between these two effects makes the planet brightest during its crescent phase. You can easily see the phases of Venus through a small telescope; high-powered, steadily mounted binoculars may also reveal its crescent.
Like Mercury, Venus is an inner planet and also never appears very far from the Sun in our sky. For comparison, Mercury's maximum apparent distance from the Sun is about 28°, while Venus can reach about 48°. Outer planets can appear 180° from the Sun at opposition.
Venus is the brightest planet in the sky. When it appears close to the Moon — the brightest object in the night sky — they create a stunning sight, even in light-polluted city skies. To find the next Moon-Venus pairing, see our regularly updated article.
Because Venus is so brilliant, many people mistake it for an airplane — or even a UFO. However, people in general have a rich imagination and often mistake many objects for aliens. Check out our infographic to see some man-made objects that have been mistaken for UFOs!
Mars: the red planet
Mars’ rusty glow makes it hard to miss — even from a brightly lit city. Its apparent brightness changes with its position in the Solar System, peaking at opposition, which occurs roughly every 26 months when Earth passes directly between Mars and the Sun.
Around its next opposition on February 19, 2027, Mars will reach its peak brightness and largest apparent size. By July 2027, it will be about nine times fainter, and its apparent diameter will be only about 40% of what it was around opposition.
Binoculars show Mars as a reddish point of light; a telescope is needed to clearly resolve its disk.

Jupiter: the largest planet with visible moons
Jupiter is the biggest planet in our Solar System and one of the brightest objects in the night sky. After Venus, Jupiter is usually the brightest planet in the sky, although Mars can occasionally outshine it near a favorable opposition. The planet is easy to spot with the naked eye, binoculars, or a small telescope. Jupiter will become brighter by the end of 2026 as it approaches opposition on February 11, 2027.
Even a small telescope or a pair of binoculars lets you feel like Galileo Galilei as you observe Jupiter and its four largest satellites — Io, Europa, Ganymede, and Callisto — known as the Galilean moons. To locate them on any given evening, try the Star Walk 2 app (requires an in-app purchase for this object type) or the Sky Tonight app, where all space objects are available for free.
In the Northern Hemisphere, Jupiter can sometimes be mistaken for Sirius, the brightest star in the night sky. From December to March, Sirius rises particularly high in the night sky, so it’s no surprise that some confuse these two bright dots. But don’t make the same mistake and remember: stars generally twinkle more strongly, while planets shine more steadily. Besides, Sirius lies far from the ecliptic.
To see the Great Red Spot — a vast storm on Jupiter — use a telescope at roughly 100× magnification or more, wait for steady atmospheric conditions, and check that the spot is facing Earth at the time of observation.
As you know, Jupiter is the largest planet in our Solar System. But just how big is it? How many Earths would fit inside this gas giant? Take our quiz and find out!
Saturn: the golden king of the rings and moons
Saturn, the fifth-brightest planet in our sky, glows with a distinctive yellow-gold hue that makes it a standout even before you use a telescope. To find it, look for a steady yellowish point of light (fainter than Venus or Jupiter).
With any small telescope, Saturn’s famous rings are usually unmistakable. With suitable magnification and good atmospheric conditions, you may also see the Cassini Division — the dark gap between the planet’s two brightest rings. When Saturn reaches quadrature — when it’s 90° from the Sun — you can even spot the planet’s shadow cast onto its rings.
Through a telescope, you can also glimpse Titan, Saturn’s brightest moon. With larger apertures, additional moons — Rhea, Dione, Tethys, and Enceladus — come into view, each appearing as a tiny, steady point of light close to the planet.
We think that the true king of the rings and moons hides many secrets that you definitely don't know yet. Take this quiz to prove us wrong!
Uranus: a pale blue dot
Uranus is extremely faint, and spotting it without a telescope is rather difficult. Even through a small telescope, it appears as a tiny, pale blue circle that blends into the background stars. Under exceptionally dark skies — Bortle 4 or darker — observers with excellent eyesight may just detect it with the naked eye if they know its exact position.
Uranus is easiest to locate when it lies near a bright reference object, like the Moon or Venus. Keep in mind, though, that the nearby Moon can easily wash out Uranus’s faint glow.
Most amateur telescopes cannot resolve Uranus’s rings or atmospheric details. However, medium to large instruments may reveal the planet’s two largest moons — Titania and Oberon — as faint, separate points of light.
Neptune: the farthest planet from the Sun
Neptune is the most challenging planet to observe. You need binoculars or a telescope to locate it. Sometimes, when Neptune is near a bright planet, you can use that planet as a guide to find Neptune. Its rings and atmospheric details are beyond the reach of visual observers using amateur telescopes. With a medium-to-large telescope and excellent viewing conditions, you may be able to discern Neptune’s color and glimpse its largest moon, Triton, as a faint point of light.
Planets visible tonight FAQ
Which planets are visible tonight?
From September 16 to 30, 2026, Venus is the brightest evening planet (but not visible everywhere), while Saturn is visible for most of the night. Mars and Jupiter appear before sunrise. Mercury becomes easier to see after sunset from southern latitudes but remains difficult farther north; Uranus and Neptune require optical aid. For your exact location, use Star Walk 2 to check what is above your horizon right now.
Why don’t planets twinkle like stars?
Planets usually shine with steadier light than stars because they are much closer to Earth and appear as tiny disks rather than pinpoints. If a bright object near the ecliptic does not twinkle much, it may be a planet.
Can I see Uranus or Neptune with the naked eye?
Uranus is technically visible to the naked eye under very dark skies, but it is extremely faint and easy to miss. You’ll need excellent observing conditions and a clear idea of exactly where to look. Neptune is too faint to see with the naked eye and requires binoculars or a telescope.
How do I know if I’m looking at Venus or Jupiter?
Venus is usually much brighter than Jupiter and often appears low above the horizon shortly after sunset or before sunrise. Jupiter is also very bright, but it can stay visible for a longer part of the night and may appear higher in the sky, depending on the season. Both shine with a steady light and don’t twinkle much like stars.
To identify them with certainty, point your phone at the object using Star Walk 2.
Why does planet visibility depend on my location?
Planet visibility depends on your location because the sky looks different in different parts of the Earth. Your latitude affects how high planets rise above the horizon, while your longitude determines when they rise and set. Local conditions also matter: buildings, mountains, trees, light pollution, and weather can hide a planet even when it is technically above the horizon.
Tips on how to see the planets: bottom line
You don't need expensive equipment to explore our Solar System — just step outside and look for the brightest "dots" in the sky. Most of the time, Venus, Jupiter, Saturn, and Mars are easily visible to the naked eye, and Mercury's visibility depends on the time of day and your location. You can also use the Moon or planetary pairings as a guide. Remember, planets usually shine more steadily than stars. For extra help, use the free Star Walk 2 app to instantly identify planets in real time.
