   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.

   Mar 30, 2020 · Satellites in a polar orbit do not have to pass the North and South Pole precisely; even a deviation within 20 to 30 degrees is still classed as a polar orbit. Polar orbits are a type of low Earth orbit, as they are at low altitudes between 200 to 1000 km. Sun-synchronous orbit (SSO) is a particular kind of polar orbit.

   What is low Earth orbit?

   • In this history of space exploration, the vast majority of human missions have been to Low Earth Orbit. The International Space Station also orbits in LEO, between an altitude of 320 and 380 km (200 and 240 mi). And LEO is where the majority of artificial satellites are deployed and maintained.

   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).

   What is a low orbit satellite?

   • Unlike geosynchronous satellites, satellites in low orbit have a small field of view and can only observe and communicate with a fraction of the Earth at a given time. This means that a large network (or constellation) of satellites is required to provide continuous coverage.

   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 marks the boundaries of low Earth orbit?

   • There's nothing innate about the Earth or its atmosphere that marks the boundaries of low Earth orbit. This is a distinction created by humans to break up all the ways an object might orbit our planet. How it's defined can vary somewhat, but we are talking about space immediately outside the atmosphere.

   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.
