This is one of the equations you need. What force provides the centripetal force? (That will be the second relationship you'll need.)sandersky said:

A circular orbit is a type of orbit in which an object, such as a satellite, moves around another object in a circular path. In a circular orbit, the distance between the two objects remains constant and the satellite maintains a constant speed.
The purpose of placing a satellite in a circular orbit is to ensure that the satellite remains in a stable and predictable path around the Earth. This allows the satellite to continuously collect data or perform its intended functions without the need for frequent adjustments to its orbit.
A satellite is typically placed in a circular orbit by using a rocket to launch it into space and then using thrusters or other propulsion systems to adjust its speed and direction until it reaches the desired orbit. The satellite's orbit is carefully planned and calculated to ensure it remains in a circular path.
The stability of a satellite in a circular orbit can be affected by various factors, such as the Earth's gravity, atmospheric drag, solar radiation, and gravitational forces from other celestial bodies. These factors can cause the satellite's orbit to deviate from a perfect circle, but engineers can account for these factors when planning the satellite's orbit to maintain its stability.
The lifespan of a satellite in a circular orbit can vary depending on its altitude and the factors mentioned above. However, with proper planning and maintenance, a satellite can remain in a circular orbit for decades or even longer. Eventually, the satellite may experience orbital decay and fall back to Earth or be intentionally deorbited to prevent space debris.
