What does retrograde mean? Why planets seem to move backwards

Retrograde means “moving backwards”. When astrologers or astronomers say a planet is retrograde, they mean that from Earth it appears to drift backwards through the zodiac for a while. The planet is not turning around. It only looks that way, and the reason has to do with how orbits work. This guide explains the geometry, how long each planet stays retrograde, what the sky looks like, and how astrologers interpret it.

The motorway analogy

Imagine two cars on a motorway. You are in the slower one, and a faster car overtakes you. As it passes, it seems to slide backwards for a moment against the trees and signs, even though it is moving forward the entire time. Planets and Earth are doing exactly that on enormous circular tracks around the Sun.

Why outer planets turn retrograde

Mars, Jupiter, Saturn, Uranus, Neptune and Pluto all orbit outside Earth’s path, and Earth moves faster than they do. Every so often Earth catches up with one of them and passes it. Around that time the planet appears to slow down, stop, and drift backwards before resuming its forward motion. This always happens close to the time the planet is opposite the Sun in the sky, which is also when it is at its closest and brightest.

Why Mercury and Venus turn retrograde

Mercury and Venus orbit inside Earth’s path and move faster than we do. They overtake Earth, passing between us and the Sun. At that point they seem to reverse for a few weeks. The result looks the same but the geometry is reversed: they are lapping us instead of us lapping them.

Stations: the pauses in between

Just before and just after a retrograde the planet seems to stand still against the stars for a few days. Astronomers call these points stations. A planet “stations retrograde” when it stops moving forward and starts to back up, and “stations direct” when it stops and resumes forward motion. Astrologers consider the days around a station especially potent because the planet barely moves, so it sits at the same degree of the zodiac for longer.

How often each planet turns retrograde

• Mercury: about three times a year, for roughly three weeks each time.
• Venus: about every 19 months (584 days), for around 40 days.
• Mars: about every 26 months, for around two months.
• Jupiter: once a year, for about four months.
• Saturn: once a year, for about four and a half months.
• Uranus, Neptune and Pluto: once a year each, for about five months.

The Sun and Moon never go retrograde, because we see them moving steadily in one direction. The lunar nodes are the exception that proves the rule: astrologers usually show them moving backwards almost all of the time, which is a separate calculation based on the Moon’s orbit.

What astrologers say a retrograde means

Astrologers read the planet’s themes as turning inward during a retrograde. Mercury is linked with communication and plans, Venus with relationships and values, Mars with drive and action, Jupiter with growth and belief, Saturn with responsibility and structure. A retrograde is treated as a time to review, revise and complete rather than to push ahead with something new. The framework is symbolic. It is not a scientific prediction of events, and many people go through retrogrades without noticing anything unusual.

Retrograde planets in your birth chart

If a planet was retrograde on the day you were born, your chart marks it ℞. Because the outer planets are retrograde for a large share of every year (about 30 to 45 percent), most people are born with at least one retrograde planet. Roughly one person in five has Mercury retrograde, one in fourteen has Venus retrograde and one in eleven has Mars retrograde. Astrologers interpret a natal retrograde as that function working in a more inward, individual or delayed way. It is not a defect. Many astrologers describe retrograde planets as a source of depth. You can see which of yours were retrograde in the solar system view of your birth chart, where the retrograde planets glow.

How to see it yourself

You can watch a retrograde unfold in our solar system view: set the time to run forward and follow the line from Earth to a planet. When Earth overtakes it, the line swings backwards. You can also plot a planet’s position against the zodiac over several months and see the loop it traces, which is how the retrograde ribbons on the birth chart page are drawn.
