What is the Period of a Satellite at 90km Above the Moon's Surface?

In summary, the period of a satellite is the time it takes for the satellite to complete one full orbit around its parent body. It can be calculated using Kepler's Third Law and is primarily affected by the mass of the parent body and the distance between the satellite and its parent body. The period of a satellite is not constant and can change over time due to various factors. It is inversely proportional to its speed and is also affected by the distance and mass of the parent body.

What is the period of a satellite circling the Moon at a height of 90km above the Moon's surface?

Can someone get me started please?

i had most of it but was forgetting to add the R of the moon to the distance of the sat above the moon >.<.
 

1. What is the period of a satellite?

The period of a satellite is the time it takes for the satellite to complete one full orbit around its parent body, such as a planet or moon.

2. How is the period of a satellite calculated?

The period of a satellite can be calculated using Kepler's Third Law, which states that the square of the orbital period is directly proportional to the cube of the semi-major axis of the orbit. This law applies to all objects orbiting a central body, including satellites.

3. What factors affect the period of a satellite?

The period of a satellite is primarily affected by the mass of the parent body and the distance between the satellite and its parent body. The mass of the satellite itself can also have a minor effect on its period.

4. Is the period of a satellite constant?

No, the period of a satellite can change over time due to various factors such as the gravitational pull of other nearby objects, atmospheric drag, and changes in the orbital parameters of the parent body.

5. How does the period of a satellite relate to its speed?

The period of a satellite is inversely proportional to its speed. This means that as the period increases, the speed of the satellite decreases, and vice versa. This relationship is also affected by the distance between the satellite and its parent body and the mass of the parent body.
