Unexpected discovery of a space rock with a thin atmosphere in a corner of the solar system

So, astronomers have made a fascinating discovery of a space rock named 2002 XV-93, which has a surprisingly thin atmosphere! This rock, about 550 kilometers in diameter, is the first object beyond Neptune's orbit to show signs of an atmosphere, which is quite remarkable given its size. The atmosphere is so thin that it could completely evaporate in about a thousand years, yet it was detected through the light of a star it passed in front of. This finding opens up exciting questions about the activity of icy objects in the outer solar system.
