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

the orbital radius of the satellite

its the mass of the satellite

Apologies for the confusion. You are correct, the factor that is not needed when calculating the velocity of a satellite orbiting a planet is the mass of the satellite. The velocity of a satellite depends on the mass of the planet, the orbital radius of the satellite, and the universal gravitational constant. The mass of the satellite itself does not affect the velocity of its orbit.

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

The factor that is not needed when calculating the velocity of a satellite orbiting a planet is the mass of the satellite. To determine the velocity of a satellite in orbit, you only need three factors: the orbital radius of the satellite, the universal gravitational constant, and the mass of the planet.

The formula to calculate the velocity of a satellite in orbit is as follows:

v = √(G * M / r)

Where:
- v is the velocity of the satellite
- G is the universal gravitational constant (approximately 6.674 × 10^-11 m^3/kg/s^2)
- M is the mass of the planet
- r is the orbital radius of the satellite

As you can see from the formula, the mass of the satellite does not play a role in calculating the velocity. The velocity of the satellite depends solely on the mass of the planet it is orbiting, the distance between the center of the planet and the satellite (orbital radius), and the universal gravitational constant.
