Q1) What is a Geostationary Orbit?

Geostationary orbit is a type of geosynchronous orbit of a satellite whereby it moves with the same speed as the rotation of the Earth. Because it orbits at the same speed as Earth revolves, a geostationary satellite seems to be stationary if seen from the surface of the Earth.
