Artificial_satellites_in_retrograde_orbit
Artificial satellites in low inclination orbits are rarely placed in retrograde orbit.[1][2] This is partly due to the extra velocity (and propellant[3]) required to launch into orbit against the direction of the Earth's rotation.
Most commercial Earth-observing satellites use retrograde Sun-synchronous orbits to ensure that observations are performed at the same local time each pass of any given location,[4] while almost all communication satellites use prograde orbits.[5]
