Newton’s law of gravitation states that the gravitational force between two point masses of magnitudes and is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.
A geostationary orbit is a circular orbit around the Earth where a satellite remains above the same point on the Earth at all times. It has the same orbital period as the Earth’s rotation (), orbits in the equatorial plane, and moves in the same direction as the Earth’s rotation (west to east).
