Retrograde planets 2026

Why the lengths differ so much

Retrograde length is a function of relative speed, not of importance. Mercury orbits in 88 days and laps Earth roughly every four months, so its apparent reversal is quick and frequent — about three weeks, three times a year. Saturn takes 29 years to orbit and barely moves against us at all, so Earth’s own motion dominates the geometry and Saturn appears to reverse for over four months every single year.

That is worth holding onto when you read that a planet is retrograde. For Saturn it is close to the default condition — roughly a third of all time. A rule that treats it as an exceptional window is treating a third of your life as exceptional.

The Sun and Moon never do this

Neither the Sun nor the Moon can be retrograde as seen from Earth, because neither is being overtaken — the Sun is what we orbit and the Moon orbits us. Any chart or app showing a retrograde Sun is showing an error. The same is true of the lunar nodes in the opposite direction: they are always retrograde by construction, which makes the label meaningless for them.
