The mean diameter of Uranus is about 3.98 times the mean diameter of Earth. Selected basis: approximate values.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
50,720 km - Mean diameter; approximate.
Uranus is an ice giant planet with a blue-green atmosphere, orbiting the Sun on its side.
Mean-radius spherical model for Uranus; actual shape is not perfectly spherical. Gravity refers to a conventional atmospheric level, not solid ground.
