Earth
12,740 km - Mean diameter; approximate.
Earth is the rocky planet on which we live and the third planet from the Sun.
Mean-radius spherical model for Earth; actual shape is not perfectly spherical.
NASA JPL — planetary physical parametersThe mean diameter of Jupiter is about 11 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.
