Titania (moon)

space Maturity 5-7 Next article →

Titania is the largest moon orbiting the planet Uranus. It is also the eighth-largest moon in our entire Solar System.

This moon is very important for helping us understand the Uranian system. Its diameter is about 1,578 kilometers. It orbits inside the magnetosphere, which is the magnetic area around Uranus. Because it is inside this area, the moon is hit by plasma. This plasma is a group of charged particles that moves with the planet. This constant hitting can change the color of the moon's surface.

Scientists believe Titania has a very interesting inside. It is likely made of equal parts rock and ice. The moon may be differentiated, which means its materials have sorted into layers. It probably has a rocky core at the center. This core might be covered by a thick icy mantle.

Some researchers think a layer of liquid water might exist there too. This water might hide at the boundary where the core meets the mantle. If there is ammonia in the ice, it could act like antifreeze. This might keep the water liquid even in the cold.

We have learned a lot about Titania through history. William Herschel discovered the moon on January 11, 1787. He found it on the same day he found Oberon. Oberon is the second-largest moon of Uranus. The name Titania comes from a character in a play by William Shakespeare. She is the queen of the fairies in "A Midsummer Night's Dream." Later, John Herschel suggested the names for the moons in 1852. These names were inspired by the works of Shakespeare and Alexander Pope.

Titania has many unique features on its surface. It has many impact craters from rocks hitting it in space. The largest crater is named Gertrude and is 326 kilometers wide.

The surface is also cut by enormous canyons called chasmata. One huge canyon is called Messina Chasma. It runs from the equator almost to the south pole. These canyons likely formed when the inside of the moon expanded. The surface is also dark and slightly red in color. Infrared tools show there is water ice and frozen carbon dioxide there.

Learning about Titania is like solving a giant puzzle. We only saw it up close one time. The Voyager 2 spacecraft flew past it in January 1986. This mission took images that mapped about 40% of the surface.

Most of what we know comes from these photos and other tools. You can even see Titania from Earth with a very good amateur telescope. It orbits Uranus every 8.7 days. Because it is tidally locked, one side always faces the planet. This means we always see the same face from Uranus.
