A satellite is orbiting around the earth with orbital radius R and time period T. The quantity which remains constant is

A satellite orbiting Earth with a specific orbital radius and time period exhibits a consistent relationship between its time period and orbital radius. According to Kepler’s third law, the square of the satellite’s orbital period is directly proportional to the cube of its orbital radius. This means that the ratio of the square of the time period to the cube of the radius remains constant for any satellite orbiting the same central body, such as Earth. This principle reflects the uniformity of gravitational influence and orbital mechanics in determining the motion of satellites around a planet.
