When Was Chiron Last in Aquarius?
Updated October 5, 2026
As of October 2026, the last time was 2005–11: Chiron first entered Aquarius on 21 February 2005 and, because retrograde motion carried it back and forth across the sign's boundary, entered it three times in all before leaving for good on 8 February 2011. Next: Chiron first enters Aquarius on 3 April 2055; retrograde motion carries it back and forth across the sign's boundary, so it enters three times in all and leaves for good on 17 December 2061.
Each bar runs from first entry to final exit. Stretches marked with a neighbouring sign are times it crossed back over the boundary before returning.

How these dates were found
With Horoskopos's sky search: Chiron's geocentric, apparent, tropical ecliptic longitude, computed with the open-source Astronomy Engine library, with each sign boundary found to the minute. Sample ingresses agree with NASA JPL's Horizons ephemeris to within about two and a half hours. Chiron is computed from orbital elements bundled for 1800–2100, so its dates are limited to that span.
