surface gravity
Ground-level gravitational strength
Surface gravity is the gravitational acceleration experienced at the surface of a celestial body—how strongly that body pulls objects toward its center.
Earth's surface gravity is the baseline for comparison; the Moon's is about one-sixth as strong, Jupiter's more than twice as strong.
Surface gravity determines how much you would weigh on different planets: Astronauts experience lower surface gravity on the Moon.
