“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 scientists at the Southwest Research Institute discovered a 29th moon orbiting Uranus while using infrared detection through the Webb Space Telescope.

Even though S/2025 U1 is pretty tiny, measuring only 10km wide, the team behind the moon spotting say that it's big news.
