Key Facts
Meet Ariel, Uranus's Neighbor!
Ariel is a moon that goes around the planet Uranus. It's the fourth-biggest moon of Uranus, which is a giant planet made of gas. Ariel is like a big, icy ball flying through space. It's not as big as Earth's moon, but it's still pretty large! Think of it like a big playground compared to a tiny pebble.
When Was Ariel Discovered?
Ariel was found a long, long time ago, in 1851, by a sky-watcher named William Lassell. He used a powerful telescope to see it. Ariel got its name from a character in a story. It took many years for scientists to learn more about Ariel because it's so far away from Earth.
What's Ariel Made Of?
This moon is made of about half ice and half rock, like a giant frozen snowball mixed with dirt. It's pretty cold out there! Ariel has a bumpy surface with big cracks and canyons, some of them as deep as a tall building is high. It's like the moon has had a rough time, but it's still super interesting!
Ariel's Wobbly Ride!
Ariel has a very strange way of going around Uranus. It spins and orbits in a way that makes it have super long summers and winters, like a crazy roller coaster! This makes Ariel a very special moon to study because it shows us how different moons can be.
