Geostationary orbit satellites travel at about ____ km per second.
Show answer & explanation
Correct answer: D
Explanation
A geostationary orbit is an orbit in which satellites move at a speed equal to the speed of the Earth's rotation. This orbit is situated at an altitude of approximately 35,786 kilometers above the Earth. In this orbit, satellites appear to remain stationary over a single specific location on the Earth. Such satellites are utilized for communication, weather forecasting, and broadcasting services. To maintain its position in a geostationary orbit, a satellite must orbit the Earth at a speed of approximately 3 kilometers per second.
