WebFurther possibilities are: (c) Tidal torques from the Sun have increased the angular momentum of the Earth; (d) Radiation pressure from the Sun changes the orbit; (e) drag from the interplanetary medium slows the Earth. 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.
