Earth’s Orbital Precession - NASA

WebTwo medium Earth orbits are notable: the semi-synchronous orbit and the Molniya orbit. The semi-synchronous orbit is a near-circular orbit (low eccentricity) 26,560 kilometers from the center of the Earth (about 20,200 kilometers above the surface). A satellite at this height takes 12 hours to complete an orbit. WebThe orbital eccentricity (or eccentricity) is a measure of how much an elliptical orbit is ‘squashed’. It is one of the orbital elements that must be specified in order to completely define the shape and orientation of an elliptical orbit..
