Upcoming Comets: Visibility and Sightings This Autumn
Originally Published 3 months ago — by WRAL.com
Astronomers are monitoring three comets this fall, but only Comet Lemmon (C/2025 A6) might become visible to the naked eye under dark skies, while the others, C/2025 R2 (SWAN) and C/2025 K1 (ATLAS), are too dim for unaided viewing. Comet Lemmon is expected to brighten as it approaches perihelion in November, but visibility depends on its actual brightness, which remains uncertain.
