What Is Surface Gravity?
Surface gravity is the gravitational acceleration at the surface of a celestial body. It depends on the body's mass and radius.
How is it calculated?
How Is It Calculated?
g = G × M ÷ r²
M: the body's mass, r: its radius.
- Enter the mass and radius.
On Earth g ≈ 9,81 m/s².
Frequently Asked Questions
Why is gravity low on a small body?
As mass decreases, surface gravity decreases; that is why gravity is very weak on small moons and asteroids.
