Distances and Diameter The average distance from the sun in miles is about 1.8 billion miles. The average distance from the sun in AU is between 18.3 and 20.1 miles. Perihelion distance: 1,703,360,000 miles. Aphelion distance: 1,866,360,000 miles. The diameter of Uranus is 13,763 miles.
Rotational And Orbital Periods Rotational Period: 17 hours, 14 minutes Orbital Period: 84 Earth years
Composition, Atmosphere, And Surface Uranus’s composition is mostly hydrogen, helium, and methane. Uranus’s atmosphere is also made of hydrogen, helium, and methane. Uranus’s surface has no craters, as well as no channels or other markings on the surface.
Size, Gravity, and Mass compared to Earth Size compared to Earth: 4 times the size of Earth Gravity compared to Earth: 90 percent more gravity Mass compared to Earth: 14 ½ times larger
Discovery and Name Meaning Uranus was discovered in 1781. It was discovered by William Herschel. Uranus’s name means The Roman Gods of Heavens.
