When Was Neptune Last in Capricorn?
Updated October 5, 2026
As of October 2026, the last time was 1984–98: Neptune first entered Capricorn on 19 January 1984 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 27 November 1998. Next: Neptune first enters Capricorn on 4 January 2148; retrograde motion carries it back and forth across the sign's boundary, so it enters four times in all and leaves for good on 31 October 2162.
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 Neptune-in-Capricorn pass, 1600–2600
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.
