Size comparison: Earth vs Uranus

Size comparison between the two blue planets, with Earth on one side and Uranus on the other.

Uranus is 4 times larger than Earth. It takes 84 years for Uranus to orbit the sun. Suffice to say that if we lived on this planet, we would reach an average of one (local) year in terms of life expectancy. The gravity on the surface of Uranus is quite close to that of Earth. An impressive number of satellites revolve around this gas giant. Its atmosphere is mainly composed of hydrogen.

Note: if one of the objects is not visible, it just means that it is too tiny to be displayed compared to the other one.
