   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.

   What is low Earth orbit (LEO)?

   • In very simple terms, low Earth orbit (LEO) is exactly what it sounds like: An orbit around the Earth with an altitude that lies towards the lower end of the range of possible orbits. This is around 1,200 miles (2,000 kilometers) or less. The majority of satellites are to be found in LEO, as is the International Space Station (ISS).

   Does Earth have a smooth orbit?

   • However, the surface of Earth is not entirely smooth, and even a perfectly circular orbit can vary in altitude. An object is said to be in low Earth orbit if it completes a revolution every 128 minutes or less. A 128-minute orbit, according to Kepler's third law, works out to a semi-major axis of 8,413 km (5,228 mi).

   How do you know if an object is in low Earth orbit?

   • An object is said to be in low Earth orbit if it completes a revolution every 128 minutes or less. A 128-minute orbit, according to Kepler's third law, works out to a semi-major axis of 8,413 km (5,228 mi). Such an object with less than 0.25 eccentricity (a roughly circular orbit), therefore, would have an average altitude of 2,042 km (1,269 mi).

   What happens if an object reaches a low-Earth orbit?

   • Technically, objects in low-Earth orbit are at an altitude of between 160 to 2,000 km (99 to 1200 mi) above the Earth’s surface. Any object below this altitude will being to suffer from orbital decay and will rapidly descend into the atmosphere, either burning up or crashing on the surface.

   Can sub-orbital objects reach low Earth orbit?

   • Things are further complicated because sub-orbital objects can reach the space we consider low Earth orbit. However, they cannot be said to be in low Earth orbit because they don't complete a circuit before falling back to Earth. Why Is LEO Important? As mentioned above, most objects we send into space are headed for low Earth orbit.
