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]
Low Earth orbit (LEO): geocentric orbits with altitudes below 2,000 km (1,200 mi). [7] Medium Earth orbit (MEO): geocentric orbits ranging in altitude from 2,000 km (1,200 mi) to just below geosynchronous orbit at 35,786 kilometers (22,236 mi). Also known as an intermediate circular orbit.
Fuel consumption increases exponentially the closer to Earth the orbit is. The International Space Station (ISS) originally orbited at an average of 350 km (217 mi) from Earth, but was boosted to an average of 400 km (248 mi) in 2011. [14] This allowed the ISS to go from an average fuel use of 8,600 kg per year to 3,600 kg per year.
A medium Earth orbit (MEO) is an Earth-centered orbit with an altitude above a low Earth orbit (LEO) and below a high Earth orbit (HEO) – between 2,000 and 35,786 km (1,243 and 22,236 mi) above sea level.
The region below medium orbits is referred to as low Earth orbit (LEO), and is about 160 to 2,000 kilometres (99 to 1,243 mi) above Earth. As satellites in MEO and LEO orbit the Earth faster, they do not remain visible in the sky to a fixed point on Earth continually like a geostationary satellite, but appear to a ground observer to cross the ...

In order to be considered a mini-moon, an incoming body must reach Earth at a range around 2.8 million miles (4.5 million km) and at a steady space of about 2,200 mph (3,540 km/h), according to ...
GTO is a highly elliptical Earth orbit with an apogee (the point in the orbit of the moon or a satellite at which it is furthest from the earth) of 42,164 km (26,199 mi), [3] or a height of 35,786 km (22,236 mi) above sea level, which corresponds to the geostationary altitude.
