Why don't satellites crash into earth?

Well, they do eventually, when theyโ€™re done doing their jobs. If defunct satellites donโ€™t burn up on their way down, they usually land in the ocean or somewhere else away from civilization.

As for why that doesn't happen immediately, it's science, baby. Satellites are launched into space by rockets, and even though the force of gravity pulls on them, the initial velocity from the rocket is enough to counteract gravity's pull. The closer the satellite is to Earth, the faster it needs to go to stay in orbit. Sometimes they need to change orbit to avoid bumping into another satellite or other space debris, but once they're out there, satellites can stay in orbit for hundreds of years.

Basically, they have to fly outside the atmosphere. If there were any significant amount of atmosphere, the satellites orbit would decay quickly, and it would crash onto Earth.Basically, they have to fly outside the atmosphere.

Earth has 1 natural satellite and thousands of artificial satellites. the earth has 1600 satellites

All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.

The moon and other planets and their satellites are held in space by the force of gravity from other planets and satellites. If the moon tried to drift off into space, gravitational forces from the Earth will keep it from floating away. It doesn't crash into the Earth because planets and moons pull AGAINST each other and keep each other from drifting away.* * * * *Only partly true.The moon does not float away because of the action of earth's gravity - whether you view this as a force or a distirtion of space-time in the moon's path.The moon does not crash into the earth, not because of other planets or satellites, but because of the momentum of its orbit around the earth.

millions, if you count natural satellites.

space satellites are in space and earth satellites are in earth.

Why would you classify the moon and earth as satellites?

User Avatar

Mars has two natural satellites. Earth has one.

User Avatar

Mercury has no natural satellites. The only man-made satellite, which crash-landed onto the planet was Messenger.

Any satellite would have to orbit Earth outside the atmosphere. If it orbits a an altitude at which there is still a significant amount of atmosphere, it would quickly lose energy and crash towards Earth.

Satellites are beyond the atmosphere in the vacuum of space. Even at their altitude of 130 miles and higher, there's still enough of an "atmosphere" to slow down the lower satellites and to cause them to crash back to Earth. In fact, most "low Earth orbit" satellites have rocket thrusters to boost them back into the proper orbits when the friction of the almost-vacuum slows them down and drags them closer.

observation satellites are used to observer the earth and how the climate is changing.

No. The earth has one natural satellite ... the moon ... and any number of other satellites whose primary purpose is not scientific (e.g. communication satellites).

The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.

There are nine types of artificial satellites. Here is the list: Astronomical satellites, Biosatellites satellites, Communication satellites, Miniaturized Satellites, Navigational satellites, Reconnaissance satellites, Earth observation satellites, Space stations, and Weather satellites.

Earth has the most amount of satellites

User Avatar

Natural satellites: one (the Moon). Artificial satellites: several thousand.

The Earth has one "natural satellite" -- the Moon. At this time there are over 13,000 artificial satellites orbiting the Earth.

If the earth stopped rotating there would be no effect on the motion of satellites.

User Avatar

Earth has one natural satellite(the moon) and about 3,000 functional artificial satellites.

The Earth is one of the Sun's satellites.

Satellites orbit the earth for a few years then fall to earth however they are directed to fall to the sea

One can find pictures of earth satellites on the NASA Visible Earth online website. NASA Visible Earth is a catalog of NASA images of our home planet, earth. The website "Geology" is where one can also find pictures of earth satellites.
