Questions regarding Low Earth Orbit or LEO, which refers to orbits at an altitude between approximately 160 kilometers / 100 miles and 2,000 kilometers / 1,200 miles.
The exact definition of a Low Earth Orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (therefore making at least 11.25 orbits per day) and an eccentricity less than 0.25. This is a common type of orbit as it is the easiest to get into and is generally useful for satellites that don't have to spend much time imaging or sending data between places on Earth. There are exceptions, such as Starlink is an internet system in LEO.
