Answer:
An orbit is a specific path (elliptical of circular) or trajectory around a planet in which a satellite revolves. Depending on the height of the satellite's orbit above the Earth's surface, the satellite orbits are classified as below:
∙ High Earth Orbits (Height from the earth's surface >35780 km): If the height of the satellite's orbit above the earth's surface is greater than or equal to 35780 km, the orbit is called High earth Orbit
∙ Medium Earth Orbit (Height above the earth's surface 2000 km to 35780 km): If the height of the satellite orbit above the earth surface is in between 200 km and 35780 km, the orbits are called medium earth orbits.
∙ Low Earth Orbits (Height above the earth's surface: 180 km to 2000 km): If the height of the satellite orbit above the earth's surface is in between 180 km and 2000 km, the orbit are called Low earth Orbits.
