Mercury turns retrograde in Sagittarius

Mercury comes to a standstill at 6°52′ Sagittarius on 9 November 2025, 18:56 UTC, and begins to move backwards against the fixed stars.

Nothing is actually reversing. Retrograde motion is a perspective effect: Earth and Mercury are on different tracks at different speeds, and for a stretch of weeks we overtake it — or it overtakes us — so it appears to slide backwards across the sky. Astrologers have read that apparent hesitation for two thousand years, and the reading has stayed roughly the same.

Mercury governs messages, contracts, travel and the machinery of being understood, so its retrograde is the one everybody has heard of — the period when the email goes to the wrong person and the thing you thought was agreed turns out not to be. The station itself is usually the most noticeable part: motion slows to nothing before it changes direction, and things governed by Mercury tend to stall, repeat or need redoing in the days either side.
