It's about 2440 kilometers. Mercury is almost spherical, so the radius is about the same everywhere.
Mercury's radius (at the equator) = 2440km or 0.3825 x EarthsVenus' radius = 6052km or 0.9488 x EarthsEarth's radius = 6378kmMars' radius = 3397km or 0.5323 x Earths
Jupiter has about 29.3 times the diameter of Mercury (at equator).
Mercury has a radius of 2439.5km. In scientific notation, this would be 2.4x103km.
Earths mean diameter is 12756km at the equator, Mercury's diameter is 4879km. Mercury diameter is 0.3824 of Earths (if Earth is 1), or put another way, Earth diameter is 2.6 times bigger than that of Mercury.

Jupiter has about 29.3 times the diameter of Mercury (at equator).
The radius of Mercury is 2439.7 kilometers or 1515.96 miles. The diameter is twice the radius.
The circumference of Mercury at equator is 15 329 km.
The circumference at the equator is 15 329 km for the planet Mercury.
If you assume thatequatriol = equatorial raduis = radius then the equatorial radius is the radius of the spheroid measured at its equator. It would be = length of the equator/(2*pi)
Earths mean diameter is 12756km at the equator, Mercury's diameter is 4879km. Mercury diameter is 0.3824 of Earths (if Earth is 1), or put another way, Earth diameter is 2.6 times bigger than that of Mercury.
Mercury has a radius of 2439.5km. In scientific notation, this would be 2.4x103km.
Mercury's radius is 0.3825 that of Earth Jupiter's radius is 11.209 that of Earth So: (0.3825/11.209)*100 = 3.41 percent.
Mercury. The average radius of the Moon is about 1700 km, which is about three-quarters the average radius of Mercury (around 2300 km).
