Gravity of any body is directly proportional to its mass,since the mass of earth is greater than that of moon so earth has greater gravity.
If you mean what is gravity then it's the characteristic of space that causes a pair of forces between you and center of a planet, for example earth. this is what causes how much you weigh, which is also why you weigh less on the moon.
see gravity on earth / wikipedia
Earth is more massive than Mars and therefore has greater gravity.
The gravity on Earth is stronger than the gravity on Mercury.
earth
No. The earth has its own gravity. The lunar gravity causes tides on earth, but does not control earth's gravity.
Mars has approximately one third the surface gravity of the earth
Earth is hafly big, so it has gravity. Larger, it has more gravity. Smaller, it has less gravity.
Gravity is the characteristic of time and space that causes the pair of equal forcesthat attract the Earth and anything on it toward each others' centers.Interestingly enough, the exact same thing also happens on other planets as well.
-- Weight is the force that attracts objects toward each other. When wetalk about 'weight', one of the objects is usually the Earth.-- 'Gravity' is the characteristic of all mass in the universe that causes the forces.Gravity is the force whereas weight is the measurement of how much the force gravity affects something.
Neptune has slightly more gravity than Earth. It is believed that the gravity is 17% greater than Earth's.
Because the earth is bigger. More mass=more gravity
