- This tiny outer Solar System world has an atmosphere. It shouldn’t
Astronomers discovered a faint atmosphere on 2002 XV93, a tiny icy world in the outer Solar System, which is unexpected given its small size. The atmosphere is short-lived and should vanish within 1,000 years unless replenished. This finding is puzzling and has sparked interest among astronomers.
