An orbit in which a satellite travels at the same speed as the earths rotational speed is called?

Answer 1

That's a 'geosynchronous' orbit. If it also happens to be over the equator, so that

the satellite appears to stay at the same point in the sky, then it's a 'geostationary'

orbit.

Answer 2

A geostationary orbit. In this orbit, the satellite orbits the Earth at the same rate that the Earth rotates on its axis, allowing the satellite to remain fixed over the same point on the planet's surface.
