उत्तर

Some satellites that revolve around the Earth in the equatorial planes have the same sense of rotation as that of the Earth. They also have the same period of rotation as that of the Earth i.e., 24 hours. Due to this, these satellites appear stationary from the Earth’s surface and are known as geostationary satellites.
