There's no such thing as zero gravity. Weightlessness and zero gravity are two different things. The earth's gravity keeps the moon in orbit. And astronauts are generally much closer to earth than the moon is, which means that the earth's pull on them has to be much stronger.

Explanation:
Gravitational acceleration is defined as the acceleration experienced by an object due to the gravitational force of the Earth. The acceleration due to gravity is not the same everywhere on the Earth's surface. It varies slightly depending on the density of the material beneath the surface.
Reasons for variation in acceleration due to gravity:
1. Non-uniform distribution of mass: The Earth's interior is not uniformly dense. It is denser towards the center and gradually becomes less dense towards the surface. This non-uniform distribution of mass causes a variation in gravitational acceleration.
2. Shape of the Earth: The Earth is not a perfect sphere. It bulges at the equator and flattens at the poles. This variation in shape also causes a variation in gravitational acceleration.
3. Altitude: Gravitational acceleration decreases with an increase in altitude. At higher altitudes, the gravitational force of the Earth is weaker.
4. Latitude: Gravitational acceleration is slightly higher at the poles and lower at the equator due to the Earth's rotation.
Why cannot the acceleration due to gravity be zero at any point?
Gravitational acceleration cannot be zero at any point on the Earth's surface because the Earth has mass, and every object with mass exerts a gravitational force on other objects. Therefore, every point on the Earth's surface experiences a gravitational force. However, the magnitude and direction of this force vary slightly depending on the factors mentioned above.
