How high can satellites go?

How high can a satellite go, and remain a satellite of the Earth? About 500,000 miles, and at any altitude above about 150,000 miles, a satellite probably won't remain in a stable orbit.

The problem is that as the satellite gets further away from Earth, the Earth's gravitational attraction decreases; and at some point, the attraction of the Moon, or the Sun, is of significance. As the years go by, little tugs of the Sun and Moon will distort the orbit a little, and the minor distortions will eventually add up - and the satellite might fall to Earth, or crash into the Moon, or be pulled out of Earth orbit and start orbiting the Sun.

There are dozens of spacecraft that have been launched out of Earth orbit; some are in Solar orbit, so they are satellites of the SUN, not the Earth. One is a satellite of Mercury, a couple of Venus, many around Mars, some of Jupiter and one of Saturn. And two spacecraft aren't even satellites of the Sun any longer; the two Voyager space probes launched in the 70's are on a path that will never return to the Sun, and will continue on into deep space.

No - satellites do not go to the moon. Satellites orbit planets/moons/objects with gravity in space.


Why are satellites high up above the earth?

Because satellites can't stay in orbit if they're moving through air, so they have to be high enough where there's no air.

What are the names of the 2 martial satellites?

The two military satellites commonly referred to as "martial satellites" are the U.S. Navy's Global Positioning System (GPS) satellites and the U.S. Air Force's Advanced Extremely High Frequency (AEHF) satellites. GPS provides positioning and timing information for military and civilian use, while AEHF satellites enable secure communications for U.S. and allied military forces.
