Low earth orbit is only slightly above the Earth, by outer space standards, 124 - 1240 miles (200 - 2000 km) in altitude. Below 124 miles, orbits rapidly degrade, causing surface impact, and above 1,240 miles or even less, the Earth's radiation belts damage electronic equipment, necessitating special shielding. The region from 1,243 miles altitude to geostationary orbit (35,786 kilometers or 22,236 mi) is known as Medium Earth Orbit.
This keeps the radius and the speed constant. Fg = m v2 / r. Low-Earth Orbit. The Space Shuttle is an excellent example of a satellite in a low-Earth orbit. The Space Shuttle orbits about 100 km to 200 km above Earth's surface.Earth's radius is about 6 000 km so this is an increase of only about 2% or 3%.That means the force of gravity is only about 4% to 6% less than at Earth's surface.his keeps the radius and the speed constant.
