This tiny outer Solar System world has an atmosphere. It shouldn’t

A group of professional and amateur astronomers in Japan has uncovered evidence that a small, distant object in the outer Solar System is surrounded by a thin atmosphere. The finding is surprising because the object is far too small to hold onto gas for long, raising new questions about how and when this atmosphere formed. Future observations will be needed to better understand its composition and origin.
