   A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. [1] Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around 800 km (500 mi), [2] while the farthest in LEO, before medium Earth orbit (MEO ...

   Oct 12, 2024 · News •. low Earth orbit (LEO), region of space where satellites orbit closest to Earth ’s surface. There is no official definition of this region, but it is usually considered to be between 160 and 1,600 km (about 100 and 1,000 miles) above Earth. Satellites do not orbit below 160 km because they are affected by atmospheric drag.

    What is a low Earth orbit?

    • Orbits of satellites that reach altitudes below 300 km (190 mi) decay fast due to atmospheric drag. Objects in LEO orbit Earth between the denser part of the atmosphere and below the inner Van Allen radiation belt. Equatorial low Earth orbits (ELEO) are a subset of LEO.

    Is low Earth orbit very high?

    • Low Earth orbit is not very high. Yes, we think about LEO as being way up there in space—and it is indeed very high. The International Space Station orbits 400 km above the Earth’s surface. However, in terms of orbits, that’s not that far. Take a look at this python model (using trinket.io) that shows the path of the ISS around the Earth.

    Why does low Earth orbit feel weightless?

    • Despite the fact that the pull of gravity in LEO is not significantly less than on the surface of Earth (approximately 90%), people and objects in orbit are in a constant state of freefall, which creates the feeling of weightlessness. In this history of space exploration, the vast majority of human missions have been to Low Earth Orbit.

    What happens if a spacecraft goes into low Earth orbit?

    • When a spacecraft goes into low Earth orbit, it won’t stay there forever. As objects orbit the Earth, they interact with the atmosphere. There is a small air drag force similar to the forces a on a bullet shot from a gun—well the big difference is the size of the drag force. In LEO, the air is really thin and exerts just a tiny force on objects.
