Comet C/2025 A6 (Lemmon) is simply weeks away from a detailed method to Earth that might make it seen to the bare eye within the October night time sky. Learn on for spectacular views of this wandering comet and its magnificent tail as captured by astrophotographers world wide.
Astronomers found Comet C/2025 A6 (Lemmon) on Jan. 3 utilizing a 60-inch telescope situated on the Mt.Lemmon Observatory in Arizona. The comet is at the moment heading farther into the photo voltaic system and can make its closest method to Earth on Oct. 21, passing somewhat over 55 million miles (89 million kilometers) from our planet, earlier than heading on to perihelion — its closest level to the solar — on Nov. 8.
Since its discovery, the comet has brightened considerably, leaping from magnitude +21.5 in January to +7 and beyond, raising hopes that it could become visible to the naked eye from dark sky locations in the coming month if the trend continues. Remember, magnitude is the scale used by astronomers to chart the apparent brightness of an object in the night sky. The lower the number, the brighter the object. The human eye is able to see bodies with a magnitude of +6.5 under ideal dark sky conditions.
Comets are famously unpredictable. The recent brightening could be a transient outburst rather than a steady increase as the comet approaches to the sun, only time will tell.
Right now, the wandering solar system body is currently visible as a diffuse smudge of light through binoculars, while astrophotographers using specialized cameras attached to powerful backyard telescopes are already capturing breathtaking long-exposure views of the comet’s bright nucleus and twisting ion tails.

Astronomer Aleix Roig captured this image of Comet Lemmon in the moonless skies above Catalonia, Spain, on Sept. 22, revealing the haunting glow of the central coma from which flows a spectral ion trail.
“In this image, you can clearly see the comet’s greenish coma, a result of diatomic carbon (C2) fluorescing in sunlight and its developing tail extending away from the Sun,” Roig wrote in a blog post on his astronomy web site www.astrocat.information. “These options make “Lemmon” a hanging reminder of the icy wanderers that go to the inside photo voltaic system from the distant Oort Cloud.”
Jānis Šatrovskis stitched collectively a surprising timelapse view revealing the extent to which C/2025 A6 (Lemmon) traveled relative to the starfield past just some days in a while Sept. 25 from Burtnieki, Latvia.

Much more detailed views got here courtesy of astrophotographer Dan Bartlett, who imaged the comet over a number of nights to disclose how the complicated construction of its ever-shifting tail advanced over time from his yard in June Lake, California, over latest weeks. Bartlett captured the comet’s twisting ion tail wax and wane because it was buffeted by the photo voltaic wind emanating from our mother or father star.

Chris Schur produced a spectacular hour-long publicity of Comet Lemmon over Payson, Arizona, on Sept. 30.
“Whereas Comet Lemmon was merely a comfortable diffuse glow within the binoculars, lengthy publicity imaging revealed a surprising object with a beautiful teal coloured head turning right into a pair of tails – one golden hued fabricated from mud close to the top, and an extended blue streamer of fuel touring all the way in which throughout my 3 diploma vast discipline with the 8inch astrograph,” Schur instructed Area.com in an e-mail.
X user Bray Falls captured yet one more beautiful view of C/2025 A6 (Lemmon) streaking by means of the skies above Austin, Texas, in early October because the tail confirmed delicate perturbations caused by the photo voltaic wind.
Comet Lemmon is beginning to look beautiful! I took this picture this morning of the comet pic.twitter.com/cGwA4nNwcLOctober 3, 2025
Chuck’s Astrophotography posted a equally magnificent view on X, displaying unimaginable element within the tail because it sprawled out in opposition to a backdrop of distant stars on Oct. 2
Comet “C/2025 A6 (Lemmon)” will not return for 1,350 years, so I’m taking benefit now. I captured it once more this morning, Oct. 2, and it is nonetheless getting brighter. I used my Celestron RASA telescope, ZWO ASI533MC coloration digicam, and an Antlia L-Filter from Starfront Observatories. pic.twitter.com/Fg2m6j5KusOctober 2, 2025
Comet Lemmon is greatest considered within the hours previous daybreak in early October and might at the moment be discovered between the constellations Ursa Main and Leo Minor. Following perihelion on Nov. 8, Comet Lemmon will embark on a 1,351-year elliptical orbit that may see the icy physique vary out 243 instances the Earth/solar distance earlier than starting its return journey to the inside photo voltaic system.
