Define satellite and five types

A satellite is a celestial body or man-made object that orbits a larger body, typically a planet, moon, or asteroid, held in place by gravity.

A natural satellite (or moon) is a naturally occurring object that orbits a planet.
Example: Earth's Moon orbits Earth.

An artificial satellite is a human-made object launched into orbit around Earth or other celestial bodies.
Example: International Space Station (ISS).

Communication satellites relay signals for television, internet, and telephone services. They are often in geostationary orbit.
Example: Geostationary satellites like Intelsat.

Navigation satellites provide global positioning and timing signals.
Example: GPS satellites in the Global Positioning System constellation.

Earth observation satellites monitor weather, land use, and environmental changes using remote sensing.
Example: Landsat series for imaging Earth's surface.
