How it works The artificial satellite is rolled around the earth in such a way that the centrifugal or external power of its motion gives it the outside motion - but the gravitational force of the earth does not allow it to flow out of the Earth's atmosphere. Both strength balance the artificial satellite and the satellite is circling around the Earth.

The Solar System

This is different from the natural satellites, or moons, that orbit planets, dwarf planets and even asteroids. Artificial satellites are used to study the Earth, other planets, to help us communicate, and even to observe the distant Universe. The first artificial satellite was the Soviet Sputnik 1 mission, launched in Since then, dozens of countries have launched satellites, with more than 3, currently operating spacecraft going around the Earth.

There are estimated to be more than 8, pieces of space junk; dead satellites or pieces of debris going around the Earth as well. Satellites are launched into different orbits depending on their mission. One of the most common ones is geosynchronous orbit. This is where a satellite takes 24 hours to orbit the Earth; the same amount of time it takes the Earth to rotate once on its axis.

This keeps the satellite in the same spot over the Earth, allowing for communications and television broadcasts.

Ampere's Rules Geosynchronous Polar Orbits The more correct term would be near polar orbits.

Another orbit is low-Earth orbit, where a satellite might only be a few hundred kilometers above the planet. This is the altitude that the space shuttle flies at, as well as the Hubble Space Telescope. Artificial satellites can have a range of missions, including scientific research, weather observation, military support, navigation, Earth imaging, and communications.

Some satellites fulfill a single purpose, while others are designed to perform several functions at the same time.

Equipment on a satellite is hardened to survive in the radiation and vacuum of space. Satellites are built by various aerospace companies, like Boeing or Lockheed, and then delivered to a launch facility, such as Cape Canaveral.

This allows rockets to use less fuel or launch heavier payloads. Other satellites orbiting in high orbits will likely be there for millions of years. You can get more information about satellites from NASA.Well, that depends on how you define satellite! One definition of the word satellite is a body that orbits a larger body.

If you take this as the definition of satellite then the answer to our question is millions! This includes actual spacecraft, and any man-made debris that has been made during.

Artificial Satellites and Space Probes 9th - 12th In this satellites worksheet, students match the list of facts given with the artificial satellite or space probe that it describes.

4) The Moon is an artificial satellite, which was brought into the vicinity of Earth by extraterrestrials in order to carry out some unknown agenda. [Yes!] 5) The Moon is made of green cheese, and was placed in space as a NASA PR stunt. Below are the names of nine different types of satellites.

There are also nine pictures of satellites. Each picture is an example of one type of satellite. You can click either on the picture or on the name to learn more about that type of satellite, and its example.

Among other functions satellites are used to track hurricanes or predict weather by meteorologists, take pictures of planets used by scientists for study, while some are .

satellite, artificial Artificial object placed in orbit around the Earth or other celestial body. Satellites can perform many tasks, including sending back data or pictures to the Earth.

Hundreds of satellites of various types orbit the Earth. They may study the atmosphere, or photograph the surface for scientific or military purposes.
