How to use "Retro grade" in context?

Retrograde motion, more popularly known as retrograde orbit, is a natural perturbation of an exoplanet's orbit caused by the gravitational pull of the planet's parent star. Retrograde orbits have a negative elongation factor, which means they drift inward in the direction of the star. Retrograde orbits can last anywhere from days to years, but they are more common as a result of long-period planets (i.e. those lasting several hundred days).

In both astronomy and astrology, retrograde motion is used to identify aspects of a person or planet.
