9. Inside Uranus Uranus has an inner rocky core. Uranus has an inner rocky core. The core of Uranus is probably smaller than the Earth’s core. The core of Uranus is probably smaller than the Earth’s core. Uranus’s core may be small because most of the rock on the planet is floating in its ocean. Uranus’s core may be small because most of the rock on the planet is floating in its ocean. Unlike the other giant planets, Uranus radiates little heat into space from its deep interior.

10. Surface on Uranus An ocean covers most of the planet. An ocean covers most of the planet. The ocean that is on Uranus accounts for most of the planet’s volume. The ocean that is on Uranus accounts for most of the planet’s volume. The ocean most likely consists of water molecules, mixed with other elements. The ocean most likely consists of water molecules, mixed with other elements. This ocean is EXTREMELY HOT, about 6650ºC (12,000ºF). This ocean is EXTREMELY HOT, about 6650ºC (12,000ºF). The ocean on Uranus remains liquid at such a high temperature, because the pressure deep in Uranus is about five million times stronger than the atmospheric pressure on Earth at sea level. Higher pressure holds molecules in liquids close together and prevents them from spreading out to form vapor.

12. Uranian Rings Astronomers have identified ten rings of debris encircling Uranus’s equator. Astronomers have identified ten rings of debris encircling Uranus’s equator. Many of these rings are made of ice and rock boulders about the size of large beach balls. Many of these rings are made of ice and rock boulders about the size of large beach balls. Several observatories first detected five of the ten rings in 1977. Several observatories first detected five of the ten rings in 1977. Starting from the innermost ring, these five rings were called Alpha, Beta, Gamma, Delta, and Epsilon.
