When Was Pluto Last in Leo?
Updated October 5, 2026
As of October 2026, the last time was 1937–58: Pluto first entered Leo on 7 October 1937 and, because retrograde motion carried it back and forth across the sign's boundary, entered it five times in all before leaving for good on 10 June 1958. Next: Pluto first enters Leo on 25 August 2183; retrograde motion carries it back and forth across the sign's boundary, so it enters five times in all and leaves for good on 23 June 2204.
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.
Every Pluto-in-Leo pass, 1600–2800
Dates are in UTC and the Gregorian calendar; in a time zone far from Greenwich an ingress can fall on the neighbouring calendar day. Dates before 14 September 1752 are Gregorian too, though Britain and its colonies still used the Julian calendar, 10 days behind until 11 March 1700 and 11 days behind after, and began the year on 25 March.

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.
