In astrology, retrograde means a planet appears to move backward through the zodiac, as seen from Earth. Nothing actually reverses: every planet keeps moving forward in its orbit, and the backward drift is an effect of watching from a moving planet. Astrologers read a retrograde as a time when that planet's themes turn toward review, revision and the past.
The word comes from Latin, retro (backward) and gradus (step). Here's what's happening in the sky, which planets do it and how often, and how a retrograde is read in the current sky and in a birth chart.
A planet that seems to step backward
Planets normally move through the zodiac in one direction, from Aries toward Taurus and on around the wheel. That's called direct motion. For stretches of time, though, each planet seems to slow down, stop, drift back a few degrees, stop again and carry on.
The cause is perspective. Picture two runners on a track. When the runner in the inside lane overtakes, the slower runner seems, for a moment, to slide backward against the crowd in the stands, even though both are running forward. Earth and the other planets are runners in different lanes around the Sun, and the distant stars are the crowd. Our explainer on why Mercury goes retrograde walks through the geometry.
The two pauses are called stations. A planet stations retrograde as it turns backward and stations direct as it resumes. Astrologers treat the days around a station as especially strong for that planet, because it is barely moving and lingers on one degree.
Which planets go retrograde, and how often
Every planet does it. The Sun and Moon never do. Approximate figures:
| Planet | How often | How long it lasts |
|---|---|---|
| Mercury | about three times a year | about three weeks |
| Venus | about every 19 months | about six weeks |
| Mars | about every 26 months | about two to two and a half months |
| Jupiter | about every 13 months | about four months |
| Saturn | about every 12 and a half months | about four and a half months |
| Uranus, Neptune, Pluto | about once a year | five months or more |
The slower the planet, the larger the share of its time spent retrograde. Mercury is retrograde about one day in five; Saturn, a little over a third of the time. That's why Mercury retrograde gets the headlines (our Mercury retrograde page has the dates), while a retrograde Saturn barely makes the news.
The Moon's nodes, the two points where its orbit crosses the Sun's path, move backward through the zodiac almost all the time, which is why charts often mark them with an R as well.
What astrologers read into a retrograde
Each planet rules certain parts of life, and during its retrograde, astrologers say those parts turn inward: less about starting, more about reviewing what's already there. The traditional shorthand is the "re" words: review, revise, reconsider, repair, return, reconnect.
- Mercury retrograde: messages, plans, travel, paperwork and devices want more care. Our Mercury retrograde do's and don'ts keeps it practical.
- Venus retrograde: love, attraction and values come up for re-examination, and old feelings resurface.
- Mars retrograde: drive and anger are said to turn inward, and plans and old conflicts get revisited. See Mars retrograde meaning.
- Jupiter retrograde: growth, beliefs and big plans are reconsidered privately.
- Saturn retrograde: rules, duties and long-term structures come up for review.
Older astrology took a sterner view. Traditional astrologers counted a retrograde planet as weakened, one of its debilities, and William Lilly's Christian Astrology (1647) scores retrograde motion against a planet when judging its condition. Modern astrologers mostly describe a retrograde as a change of style rather than strength: the planet works more slowly, more privately and often more thoroughly.
Either way, a retrograde isn't a curse, and nothing about it calls for fear. It's a tradition about pacing, and there's no scientific evidence that it affects events at all.
Retrograde in the sky vs. in your birth chart
The word turns up in two different settings.
A retrograde transit is happening in the sky now, for everyone at once. When people say "Mercury is retrograde", this is what they mean. Astrologers look at which house of your chart the retrograde falls in to say which part of your life it touches.
A natal retrograde is a planet that was retrograde when you were born. It's a permanent feature of your chart, marked R or Rx, and it describes a style: that planet's themes worked out inwardly, revisited, or developed in your own time. Most people have at least one, usually among the slow planets. Our guide to retrograde planets in a birth chart covers each one, and you can look for the R in your own free birth chart.
Stations, shadows and the whole cycle
Astrologers often think of a retrograde as a longer cycle with five parts:
- The pre-shadow: the planet, still moving forward, first crosses the degrees it will later retrace.
- The retrograde station: it stops and turns.
- The retrograde: it backs up over that stretch of the zodiac.
- The direct station: it stops again and turns forward.
- The post-shadow: it crosses the same degrees a third time, and the cycle ends when it passes the point where the retrograde began.
For Mercury, each side of the shadow lasts about two weeks. Our guide to the Mercury retrograde shadow period works through an example.
Questions readers ask
Does retrograde mean a planet is actually moving backward?
No. Every planet always travels the same way around the Sun. Retrograde is an apparent motion: Earth and the other planet move at different speeds, so from here one seems to drift backward against the stars for a while.
What does Rx mean in astrology?
Rx, or just R, is the standard abbreviation for retrograde. Beside a planet in a birth chart, it means that planet was retrograde when you were born. In a calendar or ephemeris, it marks the days a planet is retrograde.
Is a retrograde bad?
Not in modern astrology. It's described as a period for slowing down and reviewing that planet's themes. Traditional astrology counted a retrograde planet as weaker, but even there it was one factor among many.
Can several planets be retrograde at once?
Yes, and often. Jupiter, Saturn and the outer planets each spend months of every year retrograde, so their retrogrades overlap, and it's common for four or five planets to be retrograde at the same time.
