NEW YORK (AP) — The Webb Space Telescope has spotted a new tiny moon orbiting Uranus. The new member of the lunar gang, announced Tuesday by NASA, appears to be just six miles wide. It was spotted by the telescope’s near-infrared camera during observations in February.

“No other planet has as many small inner moons as Uranus, and their complex inter-relationships with the rings hint at a chaotic history that blurs the boundary between a ring system and a system of moons,” SETI Institute researcher Matthew Tiscareno said in a statement for NASA.

NASA’s James Webb Space Telescope has found a previously unknown moon orbiting Uranus.
