Surprise! Tiny world with an atmosphere in outer solar system
Astronomers in Japan have just discovered that the tiny world 2002 XV93, orbiting in the icy reaches beyond Neptune, does have a thin atmosphere. That’s despite the fact that this space rock is just some 310 miles (500 km) in diameter. That’s about 7 times smaller than our moon.
The researchers said on May 5, 2026, that they detected the atmosphere when the tiny world passed in front of a star. Using multiple telescopes, they saw that the light from the star gradually faded instead of just suddenly winking. That’s evidence for a thin atmosphere around 2002 XV93.
