Temporarily designated as S/2025 U1, the moon is estimated to be only six-miles-wide. Astronomers using NASA’s James Webb Space Telescope discovered a new moon orbiting Uranus in images taken by Webb’s NIRCam (Near-Infrared Camera). This image shows the moon, designated S/2025 U1, as well as 13 of the 28 other known moons orbiting the planet. Uranus’ most recent moon was discovered in 2023 and designated as S/2023 U1. Like its predecessor, this newest known satellite will keep its admittedly dry title of S/2025 U1 for the time being.
