DEFINITION:
“The curved path along which a natural or artificial satellite revolves around a planet is called an ‘orbit’ ”.
EXPLANATION:
The Newton's law of gravitation has an important role in the motion of satellite in its orbit, because the gravitational pull of Earth on the satellite provides the centripetal force needed to keep a satellite in orbit around some planet.
TYPES OF ORBITS:
Low- Earth orbit.
Medium-Earth orbit.
Geostationary orbit.
Elliptic orbit.
