Satellites are outside of our atmosphere, in about 120 miles high.

First off-- it is primarily because of a little thing called gravity
until you leave the atmosphere of earth--gravity pulls you in a downward force that an airplane only compromises with to do its flight.........
Next-- there isn't anything in PERMANENT orbit around the earth-- all objects that are now circling this planet will eventually see the terminal degradation of their orbit bring them crashing to earth from where they are now-----So -- keep your eyes wide open--- soon ---they will be coming down at a rate that a lot of people are going to be amazed by--- probably even threatened by-- interesting--- huh ???

something clouted a French satellite tv for pc some years in the past and took it out, yet that became theory to be area junk, debris from yet another satellite tv for pc. in spite of the undeniable fact that it relatively is going to in all threat take place in the subsequent 2 many years or so. yet a rather good variety of the meteoric stuff up there is rather only dirt. some are the size of sand grains, some slightly larger back and an exceptionally few are the size of oranges or larger

That's not their purpose. An orbit within the atmosphere would decay too rapidly due to air resistance to be permanent. A suitable altitude for orbit is far beyond the point where there's not enough atmosphere to provide either lift for the wings or oxygen for the engines.

No unless the reach distances over 120mile above the earth and remain in a fixed geosyncronious orbit abve the earth without the help of its boosters and propellers less its just a flyng object above our clouds within the earths atmosphere.

for an object to circle the earth permanently it needs to travel at the speed of 39.900 km an hour and outside the atmosphere

in order to escape the earth's gravity, a body needs a velocity of 11.2 km/sec, called as escape velocity. the airplanes don't have that much, since they are not meant for escaping the gravity.

Gravity......
AND, to escape earth gravity, you'll have to well....have some serious engine, and some serious speed.....
about 11km / s......
11000 meters / second.....=== 39600 km/h
