SATELLITE :
A satellite is a moon, planet or machine that orbits a planet or star.
For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth.
The word "satellite" refers to a machine that is launched into space and moves around Earth or another body in space.
ARTIFICIAL SATELLITE:
Artificial satellites are human-built objects orbiting the Earth and other planets in the Solar System. This is different from the natural satellites, or moons.
They are used to study the Earth, other planets, to help us communicate, and even to observe the distant Universe.
TYPES OF SATELLITE:
- Communications Satellite
- Remote Sensing Satellite
- Navigation Satellite
- Geocentric Orbit type staellies - LEO, MEO, HEO
- Global Positioning System
- Geostationary Satellites
- Drone Satellite
- Ground Satellite
- Polar Satellite
- Nano Satellites

A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word "satellite" refers to a machine that is launched into space and moves around Earth or another body in space.
Earth and the moon are examples of natural satellites. Thousands of artificial, or man-made, satellites orbit Earth. Some take pictures of the planet that help meteorologists predict weather and track hurricanes. Some take pictures of other planets, the sun, black holes, dark matter or faraway galaxies. These pictures help scientists better understand the solar system and universe.
Still other satellites are used mainly for communications, such as beaming TV signals and phone calls around the world. A group of more than 20 satellites make up the Global Positioning System, or GPS. If you have a GPS receiver, these satellites can help figure out your exact location.
