Uranus has 27 known moons, with Oberon and Titania being the largest. The surfaces of the four largest moons are covered with craters formed by meteorites, and astronomers believe they are composed of ice and rock. Uranus has 13 dark, faint rings composed likely of ice and dust encircling its equator. Astronomers use telescopes to observe how Uranus orbits the sun in an oval path, taking 84 years to complete one revolution around a distance of approximately 3 billion kilometers from the sun. William Herschel first discovered Uranus in 1781 using a telescope.

5. Uranus Astronomers use telescopes to learn how Uranus moves across the sky. Uranus is the seventh planet from the Sun. It orbits, or goes around, the Sun in an oval-shaped path. Its average distance from the Sun is a bit less than 3 billion kilometres. Uranus is so far away that it takes 84 years for the planet to go around the Sun once!
