Which factor is not needed when calculating the velocity of a satellite orbiting a planet?(1 point)

When calculating the velocity of a satellite orbiting a planet, the factor that is not needed is:

**the mass of the satellite**

The velocity of a satellite in orbit can be determined using the formula derived from the balance of gravitational force and centripetal force, which does not include the mass of the satellite. The other factors—universal gravitational constant, mass of the planet, and orbital radius of the satellite—are necessary for the calculation.
