Comet C/2025 A6 (Lemmon) shines in the October evening sky. The long period comet was discovered by the Mount Lemmon Survey in January 2025. It has an inbound orbital period of about 1,350 years and will pass nearest to the Sun on November 8th (perihelion). The close encounter with the Sun will modify its orbit and shorten its period to 1,150 years.
