Bianca (moon)

Imagine a giant planet like Uranus is playing catch with its moons. Bianca is one of those moons! It's not a big, round planet like Earth, but more like a lumpy potato. It's super small, only about 52 kilometers (32 miles) across. That's smaller than many towns! Bianca is made of dark, rocky stuff, and it's a bit like a giant, dark snowball floating in space.

Bianca is always on the move, zipping around its giant planet, Uranus. It takes Bianca only about 9 hours to make one full trip around Uranus. That's faster than you can eat breakfast and get ready for school! It stays pretty close to Uranus, too, only about 60,000 kilometers (37,000 miles) away. That's like flying from New York to Los Angeles and back, but in space!

Bianca wasn't always known to us. It was discovered in 1986 by a team of scientists looking at pictures from a spacecraft called Voyager 2. They were like space detectives, searching for clues about Uranus and its moons. Bianca is one of Uranus's inner moons, meaning it's closer to the planet than some of its other moon friends.

One of the coolest things about Bianca is how dark it is. Scientists think it's covered in dark material, maybe from impacts with other space rocks. It's so dark that it's hard to see against the blackness of space. It's like a tiny shadow moon, always playing hide-and-seek with the sunlight around Uranus.
