How much does Uranus weigh?

The planet Uranus has a little over fourteen and a half times the mass of Earth and weighs roughly 86 septillion kilograms. Despite its much greater mass, the planet has a mean radius that is four times greater than the Earth.

Uranus has a density of 1.27 grams per cubic centimeter, which makes it the second least dense planet in the solar system.
