Artificial satellites in retrograde orbit — Artificial satellites are rarely placed in retrograde orbit. This is partly due to the extra velocity required to go against the direction of the rotation of the earth. ExamplesIsrael has successfully launched five Shavit satellites in retrograde … Wikipedia
