Q:

How long is a year on Uranus?

A:

A year on Uranus is equivalent to 84 Earth years, as it takes that long for Uranus to make one revolution around the sun. A day on Uranus is equivalent to about 17 Earth hours.

The third largest planet in the solar system, Uranus is about 31,690 miles in diameter and about 1.8 billion miles from the sun. Its rotational axis is severely tilted so that it rotates on its side. It is encircled by 11 faint, narrow rings made of rock and dust, and it has 27 moons.

British astronomer William Herschel discovered the planet in 1781. He named it Georgium Sidus in honor of Britain's King George III. German astronomer Johann Elert Bode later suggested the name change to Uranus, a reference to the ancient mythological god of the sky, Ouranos.
