It's travelling forward through space at sufficient speed to balance out the effects of gravity. Either that - or it's sufficiently far enough from Earth that gravity cannot pull it back to the surface. Here's two examples.. a TV satellite and the GPS network.
In the case of a TV satellite - it needs to 'follow' the rotation of the Earth - so that it keeps transmitting TV to the same area on the planet. TV satellites are in low orbits - and thus need to move fast enough to stop gravity pulling them back to earth.
For the GPS network - the satellites need to remain stationary in orbit - in order for accurate data to be received by devices. The GPS satellites need to remain in a static position - and thus are orbiting far enough from the Earth that gravity doesn't affect them.
What else can I help you with?
Is the Mir space stAtion still orbiting?
No. It crashed back to earth in the late 90's.
What happens to old satellites?
Old satellites orbiting near the Earth eventually fall back into the atmosphere and burn. Satellites orbiting farther away stay in orbit indefinitely.
An orbiting satellite provides data for analysis by?
sending information back to Earth for processing and analysis by scientists on the ground.
Does a gymnast have to be at least 12 to be a good elite gymnast?
not at all!! Although im 12, the gym i go to(island extreme) has elite tumblers (gymnasts) that are up to 20 years old! but to be an elite tumbler you have to have a back tuck. just having a back hand spring doesnt mean you can elite tumble. I myself just learned a back tuck running and standing and they wont let me in the class.......... hope i helped yahh:)
Why Pokemon Emerald starts again after fighting the elite 4?
i doesnt restart, it just takes you back to your home and unlocks more in game stuff
WHAT IS THE only giant planet to have a spacecraft currently orbiting it?
The Cassini Orbiter is currently orbiting the ringed gas giant, Saturn. Cassini is giving us back on Earth a glimpse at Saturn's ring system, as well as its many moons.
When you beat elite four and Gary on fire red it says the end why is that you cant get to cerulean cave then?
no it doesnt all that happens is that you go back to pallet town and then you can get mewtwo in the cave
What is the current theory for the creation of the moon?
Back when the earth was young and relatively molten, a large object about half the size of the current moon, struck the earth and took a large section of the earth with it. The object combined with the pieces of earth that were broken off and began orbiting the earth. Hence, the moon.
When is danica hall back on elite tv?
she is back on now. Check the elite tv schedule. SHE HAS RETURNED <3
Does space shuttle revolve around earth before going to other planets?
Space shuttles are not designed to go to other planets, they stay in a near earth orbit, orbiting earth several times in a mission before returning back to earth. They don't really go far from our planet.
What part of the lunar module came back to earth?
The lunar module consisted of two parts: the descent stage, which remained on the lunar surface, and the ascent stage, which carried the astronauts back to the command module orbiting the Moon. The ascent stage re-entered the Earth's atmosphere while the descent stage was left behind on the Moon.
Why scientist must carefully set the right orbital speed of a satellite orbiting earth?
Scientists must carefully set the right orbital speed for a satellite that will be orbiting Earth, so that it will orbit correctly. The wrong speed will have the satellite move too fast, or too slow, skewing information and possibly causing the satellite to fall out of orbit and back to the planet's surface.
