Question

What is the time taken by satellite to complete 1 revolution around earth?

Answer 1

Your spacecraft will leave the vicinity of the Earth, to wander through our solar system. While some satellites whiz around the world in 90 minutes, others don't seem to move at all. Weather and TV satellites seem to hover above the equator. These satellites are in geostationary orbits. So the answer you are looking for is 90 minutes.
