The Planet That Rolls Around the Sun

Uranus is tilted about 98 degrees, so it spins on its side as it orbits the Sun. A giant impact long ago may have knocked it over. Its orbit takes about 84 years, so each pole faces the Sun for about 42 years of daylight, then spends about 42 years in darkness.

Uranus is an ice giant with a deep interior of water, ammonia and methane ices around a rocky core. Methane in its atmosphere absorbs red light, giving it a blue-green color. William Herschel discovered it in 1781, the first planet found with a telescope.

Faint dark rings were discovered in 1977. Many of its moons are named after characters from Shakespeare and Alexander Pope, such as Titania and Oberon. Voyager 2 is the only spacecraft to have visited, flying past in 1986, and scientists hope to send an orbiter one day.
