| They have predicted that Uranus might have 2 new moons. https://www.nasa.gov/feature....d-moons What do you think?

| Seems like a very plausible idea, and the researchers proposing it are well qualified to make the claim.  One of the best ways to infer the existence of a small moon is by the gravitational interaction it has with the ring system -- we know this very well with studying Saturn.

| One of the moons is 4.2 km wide (the size of churyumov gerasimenko) and the other is 8 km in size.
Their Keplerian orbital elements are shown in the paper if someone wants to add them to SE. They are probably very low albedo moons (that's why hubble hasn't spotted them but has discovered the tiny moons of Pluto), so to recreate them they should look a bit like coal chunks.

| Yeah, we need somebody to add them, they should be in the next update along with Planet 9 indicators and other Retrograde objects. And new dwarf planets also.
