PIX4642714: View of satellites and debris in low orbit around the Earth - Objects in low - Earth orbit - View over Ecuador 80 per cent of recenses are in low orbit up to 2000 km above Earth. Objects in low - Earth orbit (LEO). View over the equator. Eighty percent of all catalogued objects are in low - Earth orbit (LEO), which extends to 2000 km above the Earth's surface. To observe the Earth, spacecraft must orbit at such a low altitude. The spatial density of objects increases at high latitudes / Bridgeman Images
