Comet C/2025 A6 (Lemmon)
Discovered on January 3rd, 2025, by the Mount Lemmon Survey, this non-periodic comet currently graces the skies of the Northern Hemisphere. In October 2025, it is steadily brightening and has become a wonderful target for observation with binoculars or a small telescope. By the end of the month, it is expected to reach a magnitude of around +2.5 and may even become visible to the naked eye.
Comet C/2025 A6 (Lemmon) is non-periodic — meaning it will not return in the foreseeable future. 🌌
Its orbit is highly elongated (likely hyperbolic), suggesting that this is a one-time visit to the inner Solar System. After passing perihelion (its closest point to the Sun) in November 2025, it will gradually move away and may never return — or, if its orbit is slightly elliptical, it could come back after tens of thousands of years.
In other words, this is a unique chance to see it now. ✨
