On a Low Earth Orbit?

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.

What are the characteristics of low Earth orbit?

A low Earth orbit (LEO) is an Earth-centered orbit close to the planet, often specified as an orbital period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25.

What is considered low orbit?

A Low Earth Orbit is an orbit around earth with an altitude above Earth's surface between 250 kilometers and 2,000 kilometers (1,200 miles) and an orbital period between about 84 and 127 minutes. Any objects below about 160 kilometers (or 99 miles) will experience very rapid altitude loss and orbital decay.
