Natural satellites are bodies in space that orbit larger bodies. The earth's moon is a natural satellite. These other planets in our solar system also have satellites (moons): Mars, Jupiter, Saturn, Uranus and Neptune. Jupiter has the most 67. The planets are considered natural satellites of the Sun.
Artificial satellites are man-made and launched into orbit, usually around the earth. The International Space Station is a satellite on which live research is conducted. Other types of satellites serve the following purposes:
- Monitor cloud movement to help weather forecasters
- Collect data for climate and environmental research
- Monitor environmental conditions and events such as oil spills and fires
- Receive and send radio, TV and cell phone signals
- Photograph the earth to provide image maps such as Google Earth
- Receive and send GPS signals for navigation systems
- Provide education and other services remotely to developing countries
- Allow scientists to study space via space telescopes, which provide better data than earth-based telescopes.
Satellites that always stay over the same spot on earth, for example communications satellites, have an orbit that is geosynchronous. In other words their period of orbit matches that of the earth. Other types of satellites, such as those that photograph the earth, orbit at a different rate than the earth so that they move with respect to the earth's surface.
