Low Earth Orbit (LEO): A geocentric orbit with an altitude much less than the Earth's radius. Satellites in this orbit are between 80 and 2000 kilometers above the Earth's surface.

Dec 21, 2024 · 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.

May 30, 2022 · 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.

Jan 12, 2025 · 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...

Jan 6, 2017 · Definition: 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.

The Hubble Space Telescope: The Hubble has been in low earth orbit since 1990. Due to its position outside of Earth’s atmosphere, the telescope can collect stunningly high-resolution images of deep space.

Mar 2, 2020 · A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth’s surface. It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth’s surface.

Mar 30, 2020 · A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth’s surface. LEO is considered to be under altitudes of 2000 km, this upper limit a consequence of the Van Allen belts above and the harsh environment they create.

Apr 6, 2024 · Low Earth Orbit (LEO) is a specific region of space that is relatively close to Earth, typically ranging from 160 kilometers (100 miles) to 2,000 kilometers (1,200 miles) above the Earth’s surface.
