Bright Comets Lemmon and SWAN Light Up October Skies

This week, two comets, Lemmon and SWAN, will reach their brightest and closest points to Earth, offering a rare opportunity for skywatchers to observe them. Comet Lemmon will be visible near the Big Dipper's handle and will be about 56 million miles from Earth, while Comet SWAN can be seen near the Summer Triangle, about 24 million miles away. Both comets are on vastly different orbits, with Lemmon returning in 3179 and SWAN having a 20,000-year orbit.
