Next comet visible from Earth in 2026
C/2025 R3 (PanSTARRS) was one of the main comet highlights of early 2026, but its best observing days are now behind it. As the comet recedes from both the Sun and Earth, it is moving into the southern sky and gradually becoming fainter.
Looking ahead, the next promising comet is 10P/Tempel. This short-period comet is expected to reach its peak brightness in July and August 2026. It won’t be visible to the naked eye, but it should be a good target for small telescopes.
These comets are listed by when they’re actually visible from Earth, not by their perihelion or closest‐approach dates (some aren’t observable at those moments), so refer to each comet’s visibility window highlighted in the title.
Comet in April – May 2026: C/2025 R3 PanSTARRS 🌟
- Perihelion: April 19, 2026 (mag 3.2)
- Closest approach to Earth: April 26, 2026 (mag 0.8)
- Where to observe: Northern Hemisphere (before perihelion), Southern Hemisphere (after perihelion)
Will C/2025 R3 PanSTARRS be visible from Earth?
C/2025 R3 (PanSTARRS) was one of the most interesting comets of early 2026. Around its perihelion on April 19, 2026, it became bright enough to spot under dark skies and appeared low in the twilight sky.
Now the comet is receding from both the Sun and Earth and gradually becoming fainter. Its visibility has shifted toward the Southern Hemisphere, where observers may still be able to follow it with binoculars or small telescopes under good conditions. In the Northern Hemisphere, C/2025 R3 PanSTARRS is now much more difficult to observe as it sinks lower in the sky and gets lost in twilight.

When was C/2025 R3 PanSTARRS discovered?
The comet was discovered on September 8, 2025, by the Pan-STARRS survey telescope in Hawaii. C/2025 R3 PanSTARRS is a long-period comet with an unknown orbital period. It may follow a hyperbolic path, making a single pass by the Sun before heading into interstellar space. If so, April 2026 could be humanity’s only chance to see it. Even if further calculations show the comet is still gravitationally tied to the Sun, its orbit would probably be so long that it won’t come back in our lifetimes.
Comet in early July – late August 2026: 10P/Tempel 2
- Perihelion: August 2, 2026 (mag 6.9)
- Closest approach to Earth: August 3, 2026 (mag 6.9)
- Where to observe: Both hemispheres
Will 10P/Tempel 2 be visible from Earth?
From July 2026 onward, 10P/Tempel 2 will emerge in the evening sky after sunset. The comet will be visible in both hemispheres; in the Southern Hemisphere, it will rise much higher above the horizon than in the Northern Hemisphere. Around perihelion, the comet should brighten to about mag 7.0 — easily seen with binoculars or a small telescope under dark skies.
When was 10P/Tempel 2 discovered?
Discovered on July 4, 1873, by Wilhelm Tempel, 10P/Tempel 2 is a Jupiter-family periodic comet. It orbits the Sun every 1,960 days (≈5.37 years), traveling between 1.42 AU at perihelion and 4.71 AU at aphelion.
Comet in August – September 2026: 169P/NEAT
- Perihelion: September 21, 2026 (mag 12.0)
- Closest approach to Earth: August 11, 2026 (mag 13.9)
- Where to observe: Both hemispheres
Will 169P/NEAT be visible from Earth?
In August 2026, 169P/NEAT will appear in the evening sky after sunset. In the Northern Hemisphere, it will be seen fairly high above the horizon, while in the Southern Hemisphere, it will stay much lower and be harder to spot. As the month goes on, the comet will appear closer to the Sun in the sky; in September, it will move into the morning sky and start pulling away from the Sun again. The comet is expected to reach a brightness of about magnitude 10 to 12, making it a telescopic target.
When was 169P/NEAT discovered?
169P/NEAT was discovered on March 15, 2002, by the NEAT (Near-Earth Asteroid Tracking) survey. It has a relatively short orbital period of about 4.2 years, and astronomers have suggested that it may have originated in the main asteroid belt rather than in the distant outer Solar System. It is also the parent body of the Alpha Capricornid meteor shower, which peaks in late July.
Comet in September – December 2026: 161P/Hartley–IRAS
- Perihelion: November 27, 2026 (mag 13.4)
- Closest approach to Earth: October 2, 2026 (mag 11.9)
- Where to observe: Both hemispheres
Will 161P/Hartley–IRAS be visible from Earth?
From September through late December 2026, Comet 161P/Hartley–IRAS will be on view in the evening sky. Observers in both hemispheres will have a chance to spot it, with the Southern Hemisphere getting the better view before perihelion and the Northern Hemisphere taking over afterward. The comet is expected to shine at around magnitude 10 to 14, so a telescope will be the best way to see it.
When was 161P/Hartley–IRAS discovered?
161P/Hartley–IRAS was discovered on November 4, 1983, using data from the IRAS infrared satellite and identified by Malcolm Hartley, which is reflected in its name. With an orbital period of about 21 years, 161P/Hartley–IRAS belongs to the Halley-type comets.
Comet in December 2026 – February 2027: 2P/Encke
- Perihelion: February 10, 2027 (mag 5.9)
- Closest approach to Earth: February 3, 2027 (mag 6.2)
- Where to observe: Both hemispheres
Will 2P/Encke be visible from Earth?
Beginning in December 2026, 2P/Encke will steadily brighten, reaching its peak from late January to mid-February 2027. At its brightest, the comet may approach magnitude 6, making it a good binocular target, while a telescope will provide a better view at other times.
In both hemispheres, 2P/Encke will be visible in the evening sky from early December, appearing fairly high above the horizon at first. By early February, however, it will sink lower in the evening twilight. After that, observers in the Northern Hemisphere will find it lost in the Sun’s glare, while in the Southern Hemisphere it may briefly reappear in the morning sky around mid-February.
When was 2P/Encke discovered?
2P/Encke was first discovered on January 17, 1786, by the French astronomer Pierre Méchain. In 1819, Johann Franz Encke demonstrated that several earlier comet sightings were in fact returns of the same object, which is why the comet now bears his name. Orbiting the Sun once every 3.3 years, 2P/Encke has the shortest orbital period among well-observed comets.
How to find a comet using Sky Tonight?
