# Retrograd.io

> Retrograde dates for all eight planets, Mercury through Pluto, computed from first principles with a VSOP87-class ephemeris and cross-checked against NASA JPL Horizons — not copied from a list. Station-retrograde and station-direct instants, pre- and post-shadow windows, signs, and degrees; recomputed daily.

Status as of 2026-10-16 (UTC): Venus, Saturn, Uranus, Neptune, Pluto are retrograde. Mercury is direct, in its pre-retrograde shadow; it stations retrograde in Scorpio on Oct 24, 2026.

All dates are UTC. Retrograde is an apparent (optical) reversal seen from Earth, not a physical one. The orbital dates are real and verified; the astrological meanings on the site are offered as tradition and entertainment.
