Planets - Calculate Radius

Calculator for the radiuses of Sun, Moon, Earth and the planets in kilometers, miles and compared to each other. Radius is half the diameter, it quantifies the distance from the center to the edge of the celectial body. The planetary radius is important e.g. for the calculation of the gravitational acceleration.

Radius: equatorial polar average

Please enter first the kind of radius, then enter one value. The other values will be calculated.

Example: Jupiter has about eleven times Earth's radius, slightly more for the equatorial, slighly less for the polar radius.
