Retrogrades are celestial events where a planet appears to move backward in its orbit. But, what would its antonyms be? Instead of moving backward, what terms could we use to describe planets moving forward in their orbits? There are a few options to choose from, depending on the context. For example, the terms "direct" or "prograde" may be used to describe celestial objects moving forward. These antonyms are commonly used in astrological and astronomical discussions to describe planetary motion. They are antonyms of the term "retrograde," which indicates backward motion, and they help to give a more comprehensive understanding of the language used to describe celestial events.
