Every planetary retrograde in 2026

tl;dr
  • 11 retrograde periods touch 2026, across 7 bodies.
  • Retrograde motion is apparent, not physical: no planet reverses its orbit.
  • The outer planets spend close to half of every year retrograde; Mercury manages about three weeks at a time, three times a year.

Why the outer planets retrograde for so long

A planet appears retrograde while Earth is overtaking it, or being overtaken by it, on the inside of the orbit. The slower the planet moves against the background, the longer that overtaking takes to play out - so Pluto and Neptune, which crawl, spend around 40% of every year in apparent retrograde, while Mercury, which is quick, is retrograde for only about 20 days at a time.

The share-of-year column makes the pattern plain. It is a geometric consequence of orbital speed, nothing more: the periods are set by the synodic cycle between Earth and the other planet, and they recur on a fixed schedule you can compute centuries ahead.

What the arc column means

The arc is the stretch of ecliptic longitude the planet re-covers. It moves forward through those degrees, turns back over them, then turns again and crosses them a third time. The whole passage takes far longer than the retrograde itself, which is why the same degrees stay in play for months around an outer-planet station.
