Astronomers detect atmosphere around distant trans-Neptunian object
Researchers led by Ko Arimatsu of Japan's National Astronomical Observatory announced the detection of a thin atmosphere around (612533) 2002 XV93, a trans-Neptunian object about 300-311 miles across in the Kuiper Belt. The discovery was made using three Japanese telescopes observing the object as it passed in front of a background star in 2024. The finding challenges the assumption that only large planets and moons can retain atmospheres.
