What is retrograde?
Retrograde is the apparent backward motion of a planet against the background stars as seen from Earth. This is not the planet actually reversing its orbit, but a result of Earth and that planet moving at different speeds. When Earth overtakes an outer planet, or is overtaken by an inner planet, the viewing angle from Earth makes the planet seem to drift backward for a while before moving forward again.
In Western astrology, every planet can go retrograde except the Sun and the Moon. Articles on this site have covered Mercury, Venus, and Mars retrograde, each linked to its own set of themes such as communication, relationships, or action.
Why is retrograde important in astrology?
In astrology, retrograde is often seen as a period when the themes of that planet slow down, reverse, or need to be revisited. For example, Mercury retrograde is often linked to misunderstandings in communication, technical glitches, or the need to review an old issue. Venus retrograde often relates to love, values, and relationships that need reconsideration. Mars retrograde is often associated with delays, conflict, or action taken at the wrong time.
It should be noted that this is traditional knowledge for reference, not scientifically verified. The astronomical phenomenon of retrograde is real and can be calculated precisely, but the interpretation of its meaning belongs to astrology, not natural science.
How is retrograde different from easily confused concepts?
Retrograde is easily confused with a planet "moving backward" in a physical sense. In reality, the planet does not reverse its orbit around the Sun; only the view from Earth changes. Retrograde is also different from "conjunction" or "opposition", which are angles formed by the relative positions of celestial bodies. Retrograde refers to apparent direction of motion, while conjunction and opposition refer to angular distance.
Additionally, retrograde does not mean "bad". In many interpretations, it is a period suitable for reviewing, fixing, or completing unfinished business rather than starting something new.
Do all planets go retrograde?
Not all celestial bodies go retrograde in the usual sense. The Sun and the Moon are not considered retrograde in astrology because they do not have the same kind of apparent backward motion against the stars. All other planets have retrograde cycles with different frequencies and durations, depending on their distance and orbital speed.
