The factor that is not needed when calculating the velocity of a satellite orbiting a planet is the mass of the satellite.

To calculate the velocity of a satellite orbiting a planet, you need to consider three factors: the mass of the planet, the orbital radius of the satellite, and the mass of the satellite itself. The universal gravitational constant is not needed when calculating the velocity of a satellite orbiting a planet. The universal gravitational constant, denoted by G, is a constant that helps determine the strength of the gravitational force between two objects. However, when calculating the velocity of a satellite in orbit, you do not need to directly involve the gravitational constant in the calculation.
