Artificial satellites are outside of the atmosphere, and therefore do not experience any friction with it. They are in the vacuum of space, where nothing will slow them down by friction. Since they have enough velocity to keep from dropping below the atmosphere of Earth, they are in a stable orbit, the same way the Moon is. However, they do not move at perfectly uniform speed. Like all satellites of all bodies, they move more speedily when they are closer to earth and less speedily when they are farther away from Earth. Their orbits can be corrected by changing their orbital velocity, but it is nearly impossible to get a perfectly circular orbit. Being in a close to circular orbit, they remain nearly uniform in velocity.

∙ 11y agoThe main reason why is because earths gravitational force is constantly moving it a round. eventually it might get closer from gravity, but the gravity keeps throwing it around. think of a tornado. the force blows the debris around in circles.

What force keeps satellite in orbit around the Earth?
There is only one main force acting on a satellite when it is in orbit, and that is the gravitational force.
How do you place a satellite in earth orbit around sun?
It would need to be launched into a tangent plane parellel to that of the earth's orbit around the sun, with the same speed of rotation around the sun
What does a satellite do when its in geostationary orbit?
it's hot. ;)
What type of orbit does a weather satellite have and why?
The polar orbit so that it can measure cold and hot points around the entire earth :)
How does gravity affect the launch and travel of a satellite?
It has to get up to 7km a second to get out of earth's orbit, then it orbits around earth.
Is the earth's natural satellite the sun?
no, the moon is the Earths natural satellite, the moon is in orbit around the Earth. The whole Earth/Moon system is then in orbit around the sun.
How is the moon a satellite to earth?
A satellite is any object that is in orbit around another object. The moon is a natural satellite of the Earth because it orbits around the Earth.
Does a satellite revolve in orbit around Earth?
Yes.
How is a satellite kept in orbit around the earth?
Gravity
How is a satellite maintained in orbit around earth?
gravity
The path of a satellite around earth is called its?
orbit
What is the speed of a satellite that moves in an eliptical orbit around the earth?
If a satellite is in an elliptical orbit around the Earth, the Earth will be at one of the focii. The speed of the satellite will then constantly be changing. It will move the fastest when it is nearest to the Earth (perigee) and slowest when it is furthest away (apogee).
What is the name of the orbit of the satellite around the earth?
A Geostationary orbit - it means that the satellite will always stay above the same point on Earth. Hope that helps
What is a object that travels in an orbit around earth?
A satellite, or the moon.
What is a satellite orbit?
A satellite's orbit is just the path it follows around the Earth or some other planet.Satellites' orbits can be elliptical or circular.
What force keeps satellite in orbit around the Earth?
There is only one main force acting on a satellite when it is in orbit, and that is the gravitational force.
What do you call the path around the earth which a satellite follows?
Its called an orbit.
