retrograde

retrograde Used in a planetary context to denote a body moving in the opposite sense to that of most solar-system bodies, i.e. clockwise rather than anticlockwise. The classic example is the retrograde rotation of Venus. Triton is in retrograde orbit around Neptune. At least four of the outer satellites of Jupiter, and one of Saturn, are also in retrograde orbits.
