C/2025 A6 (Lemmon)

• Perihelion: November 8, 2025 (mag ~8)
• Closest approach to Earth: October 21, 2025 (mag ~8)
• Where to observe: Northern Hemisphere
• Visibility forecast: At the end of October 2025, Comet Lemmon will pass as close as 0.6 AU to Earth, conveniently positioned in the evening sky for observers in the Northern Hemisphere. In October and November, the comet might reach a magnitude of about 8 and become visible through binoculars. There is also a chance that C/2025 A6 (Lemmon) will become even brighter (about magnitude 3), as such comets tend to brighten significantly near perihelion. Let's keep our fingers crossed!
• Description: C/2025 A6 (Lemmon) is a dynamically old comet, meaning it has passed close to the Sun multiple times. It was discovered on January 3, 2025, by astronomers at Arizona's Mount Lemmon Observatory, USA. Initially, the object was designated CCNG6P2; 1.5 months later, it was confirmed to be a comet and named C/2025 A6 (Lemmon).

210P/Christensen

• Perihelion: November 22, 2025 (mag 8.3)
• Closest approach to Earth: November 8, 2025 (mag 8.1)
• Where to observe: Northern Hemisphere
• Visibility forecast: In November 2025, Comet Christensen might become visible through binoculars.
• Description: 210P/Christensen is a Jupiter family periodic comet discovered by American astronomer Eric Christensen on May 26, 2003, in images taken by the Catalina Sky Survey. The comet has an orbital period of 5.7 years. Its nucleus is about 1.7 km (1.06 miles) in diameter.

24P/Schaumasse

• Perihelion: January 8, 2026 (mag 8.5)
• Closest approach to Earth: January 4, 2026 (mag 8.5)
• Where to observe: Both hemispheres
• Visibility forecast: Comet Schaumasse will reach its brightest in early 2026 and might become visible with binoculars. Before that, from November 8 to 11, 2025, the comet will be passing close to the famous Beehive Cluster (M44) in the sky, providing a good photo opportunity.
• Description: Comet 24/P Schaumasse is a periodic comet discovered by French astronomer Alexandre Schaumasse on 1 December 1911 in Nice, France. It has an orbital period of 8.18 years. The comet nucleus is estimated to be 2.6 km (1.6 miles) in diameter.

C/2024 E1 (Wierzchos)

• Perihelion: January 20, 2026 (mag 5.2)
• Closest approach to Earth: Feb 17, 2026 (mag 6.2)
• Where to observe: Northern Hemisphere (before perihelion), Southern Hemisphere (after perihelion)
• Visibility forecast: In the autumn of 2025, the comet may become visible through small telescopes or binoculars for observers in the Northern Hemisphere. Then, as the comet moves toward perihelion, it will be positioned too close to the Sun to be observable. After perihelion, it will be best observable from the Southern Hemisphere and might be visible with binoculars.
• Description: Comet C/2024 E1 Wierzchos was discovered by Polish astronomer Kacper Wierzchos on March 3, 2024, in images taken by the Mount Lemmon Survey. The comet’s orbital period is yet to be determined.

How to find a comet using Sky Tonight?

Comets are faint and fuzzy objects that are hard to detect, so it’s best to know their location for certain. The Sky Tonight app will help you quickly find any bright comet in the sky. Here’s what you need to do:

• Tap the magnifier icon at the lower part of the screen;
• In the Search field, enter the comet’s name or designatio;
• Find the comet in the search results and tap the blue target icon next to its name;
• The app will show the comet’s current location in the sky;
• Point your device at the sky and follow the white arrow to find the comet.

You can also tap the comet’s name in the search results and then go to the Events tab to view the events related to the comet: perihelion and closest approach to Earth. Tap the blue target icon next to the event to see the comet’s location at the time of perihelion or closest approach.

Next comet visible from Earth: Bottom line

The next comet to reach perihelion is C/2025 A6 (Lemmon), which may become visible via binoculars in October-November 2025. We'll keep you updated on all the news about upcoming comets.
