One big, natural satellite has been in orbit 4.5 billion years. We call it "the moon."
There are about 180 man made satellites in geosynchronous orbit. More are added every few years. In low earth orbit there are about 3000, at the present time. Older ones tend to fall back to earth, but new ones are added every few months.
The first artificial satellite was launched by the Russians in 1957.

How many artificial satellites are in orbit around earth?
yes
WE launched many artificial satellites around our Earth for different purposes .What do you think about the impact of artificial satellites and their radiation on bio diversity?
Had no effect at all, except for those satellites which were attempting to measure biodiversity.
How many satellites orbit the US?
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
How many satellites does Ganymede have?
Ganymede Jupiter's moon has 6 satellites in total from the north Pole on the Earth.
How many satellites orbit in today?
There may be as many as 25,000 artificial satellites orbiting Earth, although only around 8,300 are on record and less than 5000 are active. Our planet has only one natural satellite, the Moon.
How many satellites are revolving around the earth?
Around 6000

What is the satellite that always stays over one spot on Earth?
A "geo-synchronous" orbit is one in which a satellite orbits in exactly 23 hours 56 minutes, the same rate at which the Earth spins. So while the satellite is moving and the Earth is moving, they are moving together at the same angular speed. This only works for equatorial orbits.
What is the force that makes satellites orbit at the same height around the earth?
Gravity keeps satellites in orbit. The closer you are to the Earth, the faster you have to go to maintain your orbit. At low Earth orbit, the altitude of the Space Station, you make an orbit every 90 minutes. At the Moon's distance you need over 27 days to go around the Earth. In-between there is an altitude which matches the rate of the Earth's rotation. Many satellites orbit at this altitude.
How many satellites orbit the US?
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
How many satellites does Ganymede have?
Ganymede Jupiter's moon has 6 satellites in total from the north Pole on the Earth.
