The mean diameter of Earth is 12,742 kilometers or 7917.5 miles.
More specifically, if we quote the accurate values for the radius, it changes depending on where you measure it.
Mean radius 6,371.0 km = 3958.8 milesEquatorial radius 6,378.1 km = 3963.2 milesPolar radius 6,356.8 km = 3949.9 miles
Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter Venus' diameter = 12,104km or 0.9488 x Earths Earth's diameter = 12,756km Mars' diameter = 6794km or 0.5323 x Earths Jupiter's diameter = 142,984km or 11.21 x Earths Saturn's diameter = 120,534km or 9.45 x Earths Uranus' diameter = 51,114km or 4.01 x Earths Neptune's diameter = 49,532km or 3.88 x Earths (Pluto's diameter = 2306km or 0.18 x Earths) I included Pluto on the end there, its not classed as a planet any more though, but a dwarf planet.
Uranus is third largest. Diameter = 51115km, about 8 times that of Earths diameter.
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths diameter.
