Comet will be visible low in the West after sunset.
🌠 Don’t miss Comet Lemmon’s spectacular green glow—an ancient visitor we won’t see again for a thousand years.
💫 This week, skywatchers have a rare chance to witness Comet C/2025 A6 (Lemmon), the brightest comet of the year and a pristine relic from the solar system’s formation.
On October 21, the comet makes its closest approach to Earth—its first and only pass for over a millennium. Scientists believe Lemmon hails from the distant Oort Cloud, and its icy makeup preserves the original building blocks of our solar system, offering clues about its 4.6-billion-year history.
Discovered on January 3 by the Catalina Sky Survey using a dedicated telescope in Arizona, Comet Lemmon was initially a faint speck. However, as it neared the Sun, solar radiation turned its diatomic carbon (C₂) molecules into a vivid emerald glow. The comet’s striking tail combines ejected dust and energetic ions, showing a dynamic dance that can change in mere hours under sunlight.
For observers, October 21 is prime time: Lemmon will be visible near the constellations Scorpius and Libra, low in the western sky after sunset. Its proximity coincides with the Orionid meteor shower and a new moon, making conditions ideal for stargazing. Binoculars or simple astrophotography can reveal the glowing coma surrounding its icy core.
