L'essentiel
- Astronomers have detected a thin atmosphere around 2002 XV93, a small trans-Neptunian object beyond Pluto.
- The discovery challenges assumptions that only larger icy bodies can retain gaseous envelopes, suggesting that even modest objects may develop atmospheres through processes like cryovolcanism or impacts.
