Artificial Satellites

An Artificial Satellite is a man made object put
into orbit around another object.


They remain in orbit by a gravitational force.


For example, they orbit Earth, other planets, moons,
etc.
They all take different types of orbits depending
upon their purpose.
They include different instruments depending
upon their purpose.

All include some sort of communication device to
communicate with earth and some sort of device to
allow it to power itself.

 The
earth a natural satellite of the sun.
 All of the planets, comets, meteoroids, asteroids
and dwarf planets are natural satellites of the sun.
 The moon is a natural satellite of the earth.
 Jupiter has 64 natural satellites.

Natural Satellites orbit due to a gravitational
force exerted by its parent object.
