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 can be calculated using the equation derived from the balance of gravitational force and centripetal force, which does not depend on the mass of the satellite itself. The relevant factors include the mass of the planet, the universal gravitational constant, and the orbital radius of the satellite.
