A new tiny moon has been identified orbiting the planet Uranus, according to NASA.

The satellite, spotted by the James Webb Space Telescope , does not have a name yet and has been designated S/2025 U1.

First spotted on 2 February by the space-bound telescope, it measures roughly six miles (10km) in diameter and joins 28 other known moons orbiting the icy giant.

Maryame El Moutamid, from the Southwest Research Institute in Colorado and lead investigator on the project to study the rings and moons of Uranus, believes its tiny size is likely to be the reason why it has been invisible to telescopes until now.

"It's a small moon but a significant discovery, which is something that even NASA's Voyager 2 spacecraft didn't see during its flyby nearly 40 years ago," she said.
