Detailed explanation-1: -Orbital speed does not depend on the mass of the object in orbit.
Detailed explanation-2: -Gravity causes objects in space that have mass to be attracted to other nearby objects. If this attraction brings them together with enough momentum, they can sometimes begin to orbit each other.
Detailed explanation-3: -Therefore, the Orbital Velocity does not depend on the Mass.
Detailed explanation-4: -For a satellite revolving around the Earth, the orbital velocity of the satellite depends on its altitude above Earth. The nearer it is to the Earth, the faster the required orbital velocity. A satellite runs into traces of Earth’s atmosphere, at lower altitudes, which creates drag.
Detailed explanation-5: -The orbital velocity of the satellite depends on its altitude above Earth. The nearer to Earth, the faster the required orbital velocity. At an altitude of 124 miles (200 kilometers), the required orbital velocity is a little more than 17, 000 mph (about 27, 400 kph).
Detailed explanation-6: -Orbital velocity depends on the mass of the central body and radius of the orbit.
