# Planets - Calculate Gravity

Calculator for the gravity of Sun, Moon, Earth and the planets, in g, m/s², ft/s² and compared to each other. The gravity, gravitation or gravity acceleration tells, how strongly objects at the surface of celectial bodies are attracted and how fast they accelerate when falling down. It depends on the density of the celectial body and on the distance from its center. The value at the poles is higher than at the equator, but that difference is low. Here, average values are used.

Round to decimal places.Please enter one value, the other values will be calculated.

g has the value of 9.80665 m/s², which is the average gravity acceleration on Earth.

Example: on the surface of Earth, the gravity is almost as high as on Saturn, whereas the Sun has 28 times the gravity of Earth.
