Its called a geostationary satellite. Its quite far out, meaning its 24 hour orbit is quite long when compared with satellites closer in to earth. Is appears stationary in our skies, in the same spot throughout its orbit. This makes it a lot easier to track, a fixed dish can be used.
That is called a geosynchronous orbit.

Earth's rotation should eventually be synchronized with the Moon's orbit.
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.
A geostationary orbit is when a satellite orbits at the same speed as the Earth's rotation, allowing it to remain fixed above a specific point on the Earth's equator. This type of orbit is often used for communication satellites because they can maintain a constant connection with a specific location on Earth.
A satellite is in geostationary orbit when it orbits the Earth at the same speed and direction as the Earth's rotation. This allows the satellite to appear stationary from the surface of the Earth. Measurements of its position and velocity can confirm that it is in geostationary orbit.
A satellite in a polar orbit traces a curved path over the Earth's surface due to the rotation of the Earth beneath it. As the satellite moves in its orbit from pole to pole, the Earth rotates, causing the satellite's ground track to appear as a series of curved lines. This effect is a result of the Earth's spherical shape and rotation, which means that while the satellite follows a straight line in space, the surface of the Earth is moving underneath it. Consequently, the satellite covers different longitudinal positions as it orbits, creating a curved trajectory relative to the Earth's surface.
The area of the earth which is imaged during a satellite orbit is referred to as the satellite swath and can range in width from ten to hundreds ofkilometers. As the satellite orbits the earth a different area is covered due to the earth's rotation. The elevation of the satellite orbit is designed so that the same location will be retraced (imaged) in a period of several weeks.
In a polar orbit, the satellite travels over the Earth's poles, maintaining a fixed trajectory relative to Earth's rotation. As the Earth rotates underneath the satellite, the ground track shifts westward, allowing the satellite to cover different longitudinal areas with each pass. Since the orbit's inclination is 90 degrees, the rate of regression—the apparent westward movement of the satellite's orbit due to Earth's rotation—becomes zero, as the satellite's path remains aligned with the Earth's rotational axis. This results in consistent coverage of the same longitudinal points over time.
Because the moon doesn't spin on its axis's [doesn't have one] it is just a satellite around earth.
It would need to be launched into a tangent plane parellel to that of the earth's orbit around the sun, with the same speed of rotation around the sun
Satellites typically orbit Earth in elliptical or circular paths. The specific path depends on the satellite's purpose and altitude. Low Earth orbit satellites circle the Earth more quickly, while geostationary satellites orbit at the same rate as the Earth's rotation, appearing to stay stationary in the sky.
