New moon found orbiting Uranus

[Roadvirus]

Yeah...there was no avoiding "the joke". Sorry.
Anyway...this makes 29 moons for that planet.

Using NASA’s James Webb Space Telescope, a team led by the Southwest Research Institute (SwRI) has identified a previously unknown moon orbiting Uranus, expanding the planet’s known satellite family to 29. The detection was made during a Webb observation Feb. 2, 2025.

The newly discovered moon is estimated to be just six miles (10 kilometers) in diameter, assuming it has a similar reflectivity (albedo) to Uranus’ other small satellites. That tiny size likely rendered it invisible to Voyager 2 and other telescopes.

I started a thread here last year when they found the 28th moon.

I thought only <sic>cling-ons orbited Uranus?

I wouldn’t be surprised to eventually learn a bunch are fragments of perhaps what was once a larger moon or several larger moons.

Good theory!

Does this moon make Uranus look big?

That's not a moon, it's a cling-on.

We need a more refined definition of a moon.

 

[Chock Full o Nuts]

I prefer natural satellite. If they call something 6 miles wide a moon, then Pluto is a planet dammit!

You'll know it's a cling-on when it decloaks and fires its primary weapon at you.

Journalists love writing about Uranus.
