Pluto in Astrology

In Western astrology, Pluto represents the side of a person that breaks something down so it can be renewed, pushing buried needs and drives up into the open. Modern astrology gives it the rulership of Scorpio. In NASA JPL data for 1940–2065, each complete stay in a sign lasted about 12 to 21 years.

Pluto at a glance

• Rules: Scorpio in modern astrology; Mars rules Scorpio in the traditional scheme
• Time in one sign: median about 14.8 years; 12.01 to 20.83 years per stay (6 stays, 1940–2065)
• Retrograde: about once a year, typically for 160 days (156 to 165)
• Full circuit of the zodiac: 248 years

Astrologers call Pluto "the great renewer," and the name sums up how the tradition reads it: as the part of a person that destroys in order to renew. Intense needs and drives that were kept below the surface come up and are expressed, even at a cost to the order already in place.

Around that core the tradition groups absolutes, power, extremes, transformations and incredible feats. Two items reach past a single person: mass movements, and the need for cooperation or sharing with another, so that neither side is destroyed. The list predicts nothing. Put to one chart, it turns into questions: where does someone reach for the absolute version of something, and when is control better shared than kept?

Pluto's place among the planets in astrology dates from after its discovery, so its rulership is a modern assignment: Scorpio, a Fixed Water sign whose traditional ruler is Mars. One modern proposal names Leo as the sign of Pluto's exaltation; traditional astrology gives exaltations only to the seven classical planets. Pluto is named for the Roman god of the underworld. Its alchemical symbol was given to it on discovery, three centuries after alchemy had all but disappeared, and is read as spirit over mind, transcending matter.

Pluto takes 248 years to circle the zodiac, and its pace is far from even. NASA JPL Horizons positions for 1940–2065 contain six complete stays in a sign, from Virgo through Aquarius. The shortest stay, in Scorpio, is 12.01 years long and the longest, in Aquarius, 20.83, with a median of about 14.8. A stay starts when Pluto first crosses into a sign and ends when it leaves for good, retrograde loops included. Those six signs fill only a fraction of the 248-year circuit, so Pluto has to cross the other half of the zodiac more slowly.

Outside the loop months at either edge, a single stay gives every birth inside it the same Pluto sign. The tradition therefore reads Pluto's sign as a generation's mark, while the personal side of the placement sits in the house. Because the house depends on the time and place of birth, a chart without a birth time cannot show it, and the Houses guide goes through all twelve.

Suppose a chart has Pluto in Virgo, a Mutable Earth sign, in the fourth house. The Virgo placement says little about this person in particular, since most births across a stay of almost 16 years share it. The fourth house is the piece only this chart has, and the tradition would read Pluto's themes there: buried drives coming into view and the question of shared control, set inside that house's area of life. Astrology is an interpretive tradition, not a scientifically validated method; your own Pluto placement can be read the same way, as a source of themes and nothing firmer.

Like the Sun, every planet appears to rise in the east and set in the west each day, and retrograde has nothing to do with that. It concerns the slow drift of a planet against the stars. Most of the time Pluto drifts eastward through the zodiac, but for part of almost every year it appears from Earth to drift westward, opposite to the other bodies of the Solar System. The term describes an appearance only, since the planets in fact always orbit in one direction.

The Horizons positions for 1940–2065 show 0.99 retrograde periods a year, so nearly every year has one. Each complete period lasted from 156 to 165 days, with 160 as the typical length, which means Pluto spends about 160 days of a typical year moving backward against the stars. A natal Pluto retrograde is therefore an ordinary feature of a chart. The Sun and Moon, by contrast, never turn retrograde.

Astrological tradition takes a retrograde phase as the inward, deliberate mode of a planet. With a natal Pluto retrograde, the urge to clear away and renew may be read as pointed at the self first: the needs pressing for change are faced by the one who holds them.

To look up your own placement, Find Pluto in your birth chart. Enter the date, time and city of birth; entering them is free and does not require registering. Astrolivo calculates it in the tropical zodiac from a geocentric viewpoint. Add the birth time, and the chart also places Pluto and the other nine bodies in their houses and shows the Ascendant and Midheaven. If the time is missing, Astrolivo uses 12:00 noon, labels the chart accordingly and leaves out the Ascendant, Midheaven, houses, exact degrees and aspects. Births at high latitudes are an exception: above about 66° latitude, where Placidus, the house system Astrolivo uses, is undefined, Astrolivo shows the houses in the Whole Sign system with a visible label.

Instead of relying on a single noon position, the calculator checks for any sign changes across your entire local birth date. If the Sun, the Moon, or another planet changes sign during that local day, the result shows each possible sign for that day rather than guessing a single one.

FAQ

Is Pluto still a planet in astrology? Yes, in the astrological sense. Astronomers demoted Pluto to a dwarf planet, and an astronomer at the Paris Observatory asked how astrologers should respond. Modern Western astrology kept it as the ruler of Scorpio, and Astrolivo's birth chart includes it among the 10 bodies it shows.

Where is Pluto in my astrology chart? Your birth date settles its sign, which you share with most people born during the same multi-year stay. The house is the part that needs your birth time and place; without the time, the chart leaves houses out.
