The orbit is called geosynchronous. Check out the NASA website. Your can see all the satellites we human have put into orbit. It'll shock you!

What kind fo satalites are you taking about? Moon is considered a satalite too.
Well,it applies to both of them. The gravitational force, commonly known as the force that pulls man to the center of the earth, will provide a centripedal force for the satalite to orbit in a circle. This is due to the resultant force known as centripedal force. However, it only occur in a specific distance between the satalite and the earth and also in a specific speed at which the satalite is travelling. Of cause, the direction of the satalite at that point mus be perpendicular to the direction of the centripedal force. This is cause the satalite to orbit in circle with reference to the earth.
I am not very sure if you are talking about the geostationary satalite as well, I wil just explain it. Geostationary satalite will remain at a same vertical place on earth, for example, i stays about LA no matter what happens. This satalite will orbit in a specific velocity and specific distance from earth.

These satellites are called Geostationary satellites. They revolve about the equator in the same period of time as the earth rotates. If they are not precisely above the equator then the orbital path will be a figure-8. They do not orbit at the same speed as the rotation of the earth, but in the same period of time. 35,800 km is the altitude at which the period of a stable orbit is the same as the period of the rotation of the earth. If you determine the radius of that orbit (about 6400 km. for the radius of the earth) and add that to 35,800 km for the altitude of the orbit you get an orbital radius of 42,200 km. The circumference of a circle with that radius is 265,000 km, which is traversed in 24 hours, so the velocity is about 11,000 km/hr. That does not mean you get to a geostationary orbit more easily than a low earth orbit (28300 km/hr), but it means once you get there (by speeding up from a low earth orbit) and stabilize your orbit (you speed up again once you reach the highest point, where you now are going too slowly) your velocity will be about 11,000 km/hr.

The satellite that stays in the same place on the earth has a rotational period of 24 hours. It is known as GeoStationary Orbiter

Its a geosynchronous orbit.
It must be above the equator (for obvious reasons) and at an altitude of about 35,786km above sea level. No other orbit can be geosynchronous.

well it's technically moving at the speed of the earth's rotation to stay in the same place as viewed by us.

IT DOESNT STAY IN THE SAME PLACE ON EARTH!THE EARTH IS MOVING AND SO R U.THE SATELLITE IS MOVING SLOWLY
