Comet Tracker For Friday: When And Where To See The Two Green Comets
Comet Lemmon's orbit was shortened by Jupiter's gravity, and both comets may be visible to the naked eye under dark skies during their closest Earth approach in late October 2025.
- On October 20, 2025, Comet C/2025 A6 Lemmon and Comet C/2025 R2 SWAN will shine together, possibly visible to the naked eye, already seen in binoculars across the Northern Hemisphere.
- A close pass about 216 million miles from Jupiter tugged on Comet C/2025 A6 Lemmon, draining orbital energy and shortening its orbital period to about 1,150 years.
- Data from observation databases indicate Comet C/2025 A6 Lemmon is about 78.3 million miles from the Sun and 70.7 million miles from Earth, with magnitude 6.
- Observers in the Northern Hemisphere should use dark skies to the north and west, viewing Comet C/2025 A6 Lemmon in a 30-minute window about 90 minutes before sunrise and SWAN low after sunset, with an 86%-lit waning gibbous moon.
- As the pair appears this month, public trackers note that Comet C/2025 A6 Lemmon is currently the brighter and moving into morning northern skies, prompting daily updates from projects like The Virtual Telescope Project 2.0.

One old confidant, the other recently rediscovered: Two comets come to visit - at a safe distance.
One of them is an old confidant, the other recently rediscovered: where and when the two comets will be visible from Earth.
One was discovered only recently, the other is an old acquaintance: two comets fly past the Earth – at a safe distance.Two comets can observe stargazers and hobby astronomers especially in the second half of October in the night sky. "Swan" and "Lemmon" shine so brightly that they can be observed with the naked eye or at least with binoculars, said the chairman of the Association of Starfriends based in Bensheim, South Hesse, Uwe Pilz, the Germa…
Comet C/2025 A6 Lemmon: View from New Mexico
Comet C/2025 A6 Lemmon: View from New MexicoComet Lemmon is brightening and moving into morning northern skies. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6 (Lemmon) is now the third comet currently visible with binoculars and on long camera exposures. Comet Lemmon was discovered early this year and is still headed into the inner Solar System. The comet will round the Sun on November 8, but first it will pass its nearest to the Earth—a…
