Astronomy enthusiasts are in for a celestial treat as Comet Lemmon (C/2025 A6) will be visible from Earth on October 22. First discovered by the Mount Lemmon Survey in Arizona earlier this year in January, the comet has since evolved from a faint, fragile object into a bright and striking celestial body. In recent weeks, its coma and tail have become increasingly prominent, captivating observers worldwide.
**A Rare Visitor**
Comet Lemmon boasts an estimated orbital period of approximately 1,350 years, making its appearance a truly rare event that won’t be witnessed again anytime soon. This long interval highlights the significance of this comet’s visit for both astronomers and skywatchers alike.
**Celestial Proximity**
Comet Lemmon will make its closest approach to Earth on October 21 (UTC), which corresponds to the early hours of October 22 in India due to the +5:30-hour time difference. At its nearest, the comet will be about 89.2 million kilometers (roughly 0.60 astronomical units) away from our planet. Following this, it will reach its perihelion—the closest point to the Sun—on November 8, at a distance of approximately 79.25 million kilometers.
**How to See Comet Lemmon**
To catch a glimpse of this spectacular comet, sky watchers should look toward the northwest sky about 90 minutes after local sunset. Until mid-October, Comet Lemmon is moving through notable constellations such as Bootes, Ursa Major, and Canes Venatici, making it easier to locate.
Under ideal viewing conditions, the comet could reach an apparent brightness ranging from +3.5 to +4.4 magnitude, making it visible to the naked eye in dark, clear skies.
Don’t miss this extraordinary opportunity to witness a visitor from the outer reaches of our solar system—a celestial event that occurs just once every millennium. Grab your telescopes, step outside, and marvel at the brilliance of Comet Lemmon this October!
