Which of the following properly explains how a satellite maintains orbit around the Earth?

• The satellite is in space, and because it is in space there is no gravity so it hovers up in orbit.

• The satellite's sideways movement matches the gravitational force of Earth.

• The satellite is in an environment of zero friction, therefore it hovers forever.
