Mercury Retrograde 2026

A planet never actually reverses. "Retrograde" is a line-of-sight effect: as the faster Earth overtakes a slower planet (or, for Mercury and Venus, as they swing between us and the Sun), the planet appears to drift backward against the stars for a few weeks. Astronomers have tracked these apparent loops for millennia.

Mercury turns retrograde three or four times a year — more often than any other planet — which is why it dominates the conversation. Around its stations, plans, messages and machines are traditionally said to snag. Whatever meaning you give it, the timing itself is exact and listed below.
