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. It's low density means that the planet itself is made up predominately of ice rather than gas. Uranus is the seventh planet from the sun and is the smallest of the gas giants that are found in the outer solar system.
