# Uranus Radius

The average radius of the planet Uranus is 25,362 km or 15,759.2 miles. The reason why it is an average is because the radius is not exactly the same when measured at the equator and when measured from the North and South Pole. The radius of Uranus’s equator is 25,559 km or 15,882 miles. The radius when measured from pole to pole is 4,973 km or 15,517 miles. It is the quick rotation of Uranus (17 hours, 14 minutes and 24 seconds for a full rotation) which causes this widening at the equator.

When compared to the Earth’s average radius (6,371 km or 3,958.5 miles), Uranus’s average radius is 3.9809 times larger. Uranus’s equator radius is 4.007 times larger than Earth’s equator radius (6,378.1 km or 3,963 miles). Uranus’s pole to pole radius is 3.929 times larger than Earth’s pole to pole radius (6,356.8 km or 3,950 miles).
