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.
The distance of Venus from the sun as it orbits around is 108,000,000 kilometers (0.7 AU). It takes Venus 224.65 days to complete its orbit, which means a year on Venus is approximately 224.65 Earth days. While all planetsâ orbits are elliptical, Venusâ orbit is the only one which is closest to circular.
