When Was Pluto Last in Aries?
Updated October 5, 2026
As of October 2026, the last time was 1822–53: Pluto first entered Aries on 16 April 1822 and, because retrograde motion carried it back and forth across the sign's boundary, entered it four times in all before leaving for good on 14 February 1853. Next: Pluto first enters Aries on 18 June 2066; retrograde motion carries it back and forth across the sign's boundary, so it enters five times in all and leaves for good on 10 March 2097.
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: Pluto'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 an hour for 2023–43, about three hours for the 1850s–80s and about 15 hours for the 1770s: Pluto moves so slowly that a sliver of an arcminute in position becomes hours in time. Pluto comes from an integrated orbit that is reliable from about 1 CE to 3999 CE. Data generated 2026-10-04; page built 2026-10-05.
