Responses

the mass of the satellite
the mass of the satellite

the universal gravitational constant
the universal gravitational constant

the orbital radius of the satellite
the orbital radius of the satellite

the mass of the planet

Answer 1

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 gravitational attraction between the satellite and the planet, which does not depend on the mass of the satellite itself.
