Uranus has 21 moons and small, dusty rings. Voyager 2 acquired this view of the seventh planet while departing the Uranian system in late January 1986. This image looks at the planet approximately along its rotational pole. A Blue-Green World Voyager 2 image of Uranus, 1986 (Image:NASA)A Blue-Green World: Uranus has a thick hydrogen-methane atmosphere. Methane causes the planet’s blue-green color. Some astronomers call Uranus and Neptune ‘ice giants’ because most of their mass is ice and some rocky material. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather that its material is more or less uniformly distributed. A Blue-Green WorldHubble’s View: This image, taken by Hubble, clearly shows Uranus and its rings. Uranus’ rings are smaller and dustier than those of Saturn, and will eventually dissipate. Hubble’s View Image: NASASlide4: Deep exposure of Uranus taken with the Hubble Space Telescope reveal two small moons and two faint rings. All orbit outside of Uranus's previously known (main) ring system, but interior to the large, classical moons.Dusty Rings: This image reveals many broad lanes of dust surrounding the 9 main rings of Uranus. It was taken by Voyager 2 looking back toward the sun through the ring system. Dusty RingsTipsy?: Uranus moves around the Sun with its rotation axis is perpendicular to its orbit around the sun. It is thought that a planet-sized body hit Uranus early in its history, “tipping” it over. Because of this, Uranus’ seasons last over 20 years! Tipsy?Slide7: Earth UranusGeorge’s Star: George’s Star Uranus was discovered by William Herschel, the British royal astronomer, in 1781. Herschel thought the planet was a comet at first! He tried to name it “George’s Star” after King George.God of the Sky: The name "Uranus" was eventually proposed in order to conform with the other planetary names from classical mythology. The name didn't come into common use until 1850. To the ancient Greeks, Uranus was god of the sky and heavens. God of the SkyMissions: Missions Only one spacecraft has visited Uranus. On Jan. 24, 1986 Voyager 2 passed within 50,600 miles. Voyager 2 radioed images and scientific data on the planet, its moons, rings, atmosphere, interior and the magnetic environment surrounding Uranus. Uranus’ Moons: Uranus has 5 medium-sized moons and 21 smaller moons. The five main satellites are Miranda, Ariel, Umbriel, Tatania and Oberon. Miranda Ariel Oberon Titania Umbriel Uranus’ MoonsMiranda: Uranus’ moon Miranda has a strange fractured appearance, as if it was shattered then put back together. The high cliffs and winding valleys of the moon may indicate that Miranda was larger in the past and shrank to its current size. MirandaTitania: Picture of Titania taken by Voyager 2. Titania is 1600 kilometers in diameter. TitaniaSlide14: An artists view, this montage of images of the Uranian system was prepared from an assemblage of images taken by the Voyager 2 spacecraft during its Uranus encounter in January 1986.
