When Was Pluto Last in Libra?
Updated October 5, 2026
As of October 2026, the last time was 1971–84: Pluto first entered Libra on 5 October 1971 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 28 August 1984. Next: Pluto first enters Libra on 5 November 2217; retrograde motion carries it back and forth across the sign's boundary, so it enters three times in all and leaves for good on 14 October 2230.
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.

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.
