the mass of the planet
The factor that is not needed when calculating the velocity of a satellite orbiting a planet is the mass of the satellite itself.
When calculating the velocity of a satellite orbiting a planet, the factor that is not needed in the calculation is the mass of the satellite. The velocity of a satellite is determined based on the mass of the planet, the orbital radius of the satellite, and the universal gravitational constant.
To calculate the velocity of a satellite, you can use the following formula:
v = √(G * M / r)
where:
v = velocity of the satellite,
G = universal gravitational constant,
M = mass of the planet,
r = orbital radius of the satellite.
By plugging in the values of the mass of the planet, the orbital radius, and the universal gravitational constant into the formula, you can calculate the velocity of the satellite.
