Pholus crossed the sign of Cancer in about two years. It will stay in Capricorn for close to twenty-five. Same small body, same loop around the Sun. That gap is the most useful fact you can know about Pholus in astrology, and few guides print it. This page gives the share of time Pholus spends in each of the twelve signs. It lists the dates of its recent passes. It then shows what the gap changes when you read your own chart. I worked out every number myself. The method sits near the end, so you can check it.
Pholus is a real body with a very uneven path
Pholus is a small icy body, about 100 km wide and very red. Its catalogue name is 5145 Pholus. David Rabinowitz found it on January 9, 1992, with the Spacewatch camera at Kitt Peak in Arizona. It was the second centaur ever found, after Chiron. A centaur, in the sky, is a small body that loops through the zone of the giant planets. It is too far out to be a normal asteroid and too quiet to be a full comet.
The path of Pholus is long and thin. At its closest, it comes about 8.7 times as far from the Sun as Earth does. That is just inside the orbit of Saturn. At its farthest, it drifts out to about 32 times that distance, past the orbit of Neptune. One full loop takes about 91 years. Those figures come from the NASA JPL small-body file for Pholus.
The wider family has its own page. Our guide to centaurs in astrology covers the group as a whole.
Why Pholus races through some signs and crawls through others
Think of a swing. At the bottom of the arc it moves fast. At the top it almost stops. A body on a stretched loop does the same thing. Near the Sun it speeds up. Far from the Sun it slows down. Johannes Kepler wrote this rule down four hundred years ago, and it still holds.
For Pholus, the effect is huge. Its closest point to the Sun lies in the part of the sky we call Cancer. Its farthest point lies in the opposite part, which is Capricorn. So Pholus rushes past Cancer and Leo, then spends decades in the slow end of its loop. Seen from Earth, it seems to hang in Capricorn and the signs on each side of it.
Pholus last passed its closest point on September 11, 1991. That is why it was found a few months later. It was near the Sun, bright enough for a camera to catch. On the night it was found, it sat at 0°35′ Leo.
The measure: how much time Pholus spends in each sign
If Pholus moved at a steady pace, it would spend one twelfth of its time in each sign. That is 8.3 per cent. It does nothing of the kind. I measured ten full loops, from its return to Aries in March 1527 to its return to Aries in January 2433. That window covers 906 years. Every figure below uses that same window.
| Sign | Share of all time | Years per loop, on average |
|---|---|---|
| Capricorn | 24.9 per cent | 22.6 years. |
| Aquarius | 21.9 per cent | 19.8 years. |
| Sagittarius | 14.4 per cent | 13.1 years. |
| Pisces | 10.9 per cent | 9.8 years. |
| Scorpio | 6.8 per cent | 6.2 years. |
| Aries | 5.2 per cent | 4.7 years. |
| Libra | 3.8 per cent | 3.5 years. |
| Taurus | 3.0 per cent | 2.7 years. |
| Virgo | 2.6 per cent | 2.3 years. |
| Gemini | 2.3 per cent | 2.1 years. |
| Leo | 2.2 per cent | 2.0 years. |
| Cancer | 2.1 per cent | 1.9 years. |
Read the top of the table first. Pholus spends about one quarter of all time in Capricorn. Add Aquarius, Sagittarius and Pisces, and four signs hold 72 per cent of its time. The other eight signs share the last 28 per cent.
Now read the bottom. Pholus spends about twelve times longer in Capricorn than in Cancer. Cancer gets 2.1 per cent of the time. Capricorn gets 24.9 per cent. No planet from Mercury to Pluto shows a gap that wide.
The loops are not all the same length, and the shares move a little from one loop to the next. In my ten loops, a single stay in Capricorn ran from 19.9 to 23.7 years of net time. A stay in Cancer ran from 1.7 to 2.0 years. The ranking never changed.
I am not the first to see the gap. Robert von Heeren and Dieter Koch, two German astrologers, wrote that Pholus needs only about two years for Cancer and Leo but about 23 for Capricorn and Aquarius. They made that point in their 1995 book on Pholus. What this page adds is the full twelve-sign table, a long window, and exact dates.
When Pholus was in each sign: recent passes
The table lists each pass from the first day Pholus touched a sign to the last day it left. Near a sign border, Pholus can slip back for a few months. That happens because Earth overtakes it each year, which makes it seem to move backward. Astrologers call that backward phase retrograde. So the start and end dates of two passes can overlap.
| Sign | First entry, in UT | Last exit, in UT |
|---|---|---|
| Capricorn | Jan 22, 1928 | Nov 10, 1952. |
| Aquarius | Mar 20, 1950 | Dec 29, 1971. |
| Pisces | Apr 9, 1970 | Feb 18, 1981. |
| Aries | Apr 25, 1980 | Apr 25, 1985. |
| Taurus | Apr 25, 1985 | Apr 24, 1988. |
| Gemini | Aug 30, 1987 | May 23, 1990. |
| Cancer | May 23, 1990 | May 28, 1992. |
| Leo | Sep 21, 1991 | Jun 11, 1994. |
| Virgo | Oct 2, 1993 | Aug 21, 1996. |
| Libra | Dec 2, 1995 | Oct 19, 1999. |
| Scorpio | Oct 19, 1999 | Sep 5, 2006. |
| Sagittarius | Jan 22, 2005 | Oct 22, 2019. |
| Capricorn | Jan 21, 2018 | Nov 18, 2042. |
| Aquarius | Mar 23, 2040 | Dec 14, 2062. |
| Pisces | Mar 26, 2061 | Mar 5, 2072. |
UT means Universal Time, the clock of the Greenwich line. Four of these dates fall one day earlier in New York. Pholus first entered Capricorn at 7:02 p.m. on January 20, 2018, New York time. It will leave for good at 7:57 p.m. on November 17, 2042, New York time. It first entered Sagittarius on January 21, 2005, and last left Cancer on May 27, 1992, both in New York time.
The present pass is the long one. Anyone born from October 22, 2019, to March 23, 2040, has Pholus in Capricorn. No chart tool can argue about it. For births from January 2018 to October 2019, and from March 2040 to November 2042, the answer depends on the exact day. Check it in a chart.
Pholus is still there today. It turned direct on September 25, 2026, at 9°53′ Capricorn. Direct means it has stopped its backward phase and moves forward again. For more on the sign itself, see our page on the Capricorn sign.
What the gap changes when you read Pholus
A sign held for 20 years is shared by a whole generation. A sign held for two years is shared by a small group. That changes how much weight the sign can carry.
Take a child born in 2025. Pholus is in Capricorn, and so it is for every child in the same school, and for their younger brothers and sisters too. The sign alone says very little about that one child. What matters more is the house, which is the area of life where Pholus falls. Close angles to the Sun, Moon or inner planets matter too. Astrologers call those angles aspects.
Now take someone born in 1991. Pholus in Cancer or Leo marks a much smaller cohort. The sign is closer to a personal note. That does not make it stronger. It makes it rarer.
Here is a fair rule of thumb. When Pholus sits in Sagittarius, Capricorn, Aquarius or Pisces, read the house and the aspects first. When it sits in Cancer, Leo, Gemini or Virgo, the sign earns a little more attention. For how signs work in general, our guide to the zodiac signs is a good place to start.
The half-return: your age depends on when you were born
The same uneven speed shapes timing. A half-return is the moment Pholus reaches the point right across from where it was at your birth. Some astrologers treat that as a turning point. With a steady body, everyone would reach it at the same age. With Pholus, the age swings widely.
I measured the first exact half-return for people born on January 1 of six years. I checked each result on a second set of NASA data.
| Born on January 1 of | Pholus at birth | Age at first half-return |
|---|---|---|
| 1930 | 2°19′ Capricorn | 60.4 years old. |
| 1945 | 21°42′ Capricorn | 46.5 years old. |
| 1960 | 10°10′ Aquarius | 32.6 years old. |
| 1975 | 7°10′ Pisces | 19.6 years old. |
| 1991 | 13°06′ Cancer | 36.1 years old. |
| 2005 | 29°06′ Scorpio | 74.4 years old. |
The spread runs from about 20 to about 74 years in this small sample. Someone born in 1975 met it as a young adult. Someone born in 2005 will wait until old age. Von Heeren and Koch give a wider range, from 13 to 76, for all birth dates. My six cases sit inside it. So if you read a line such as “the Pholus half-return hits at 45,” treat it with care. It depends on your birth year.
The myth behind the name
Pholus comes from Greek myth. The main ancient account is in the Library, a Greek handbook of myths once credited to Apollodorus. Pholus was a calm, kind centaur who lived in a cave. When the hero Heracles came by, Pholus fed him. Heracles asked for wine. Pholus opened a jar that belonged to all the centaurs.
The smell of the wine drew the other centaurs. They came in a rage, and Heracles drove them off with arrows dipped in the blood of the Hydra, a poison with no cure. Later, Pholus pulled an arrow from a dead centaur. He wondered how so small a thing could kill so large a creature. The arrow slipped from his hand, struck his foot, and killed him.
Modern astrologers read two ideas from that story. The first is the lid: one small act, like opening a jar, sets loose a force far larger than the act. The second is the arrow: a tiny cause with a huge result.
Where the astrology of Pholus comes from
Be clear about one thing. Pholus has no ancient tradition. Ptolemy does not mention it in his Tetrabiblos. Vettius Valens never used it in his Anthologies. William Lilly knew nothing of it when he wrote Christian Astrology in 1647. Nobody knew Pholus existed before 1992.
Its meanings come from a handful of modern writers. The main early source is the 1995 book by Robert von Heeren and Dieter Koch, Pholus, Wandler zwischen Saturn und Neptun. The title means Pholus, the wanderer between Saturn and Neptune. Dieter Koch is also known for his work on the Swiss Ephemeris, the data that many chart sites use. The British astrologer Melanie Reinhart wrote about Pholus and the other centaurs in Saturn, Chiron and the Centaurs, first published in 2002.
These writers describe Pholus with the same few keywords. There is the small cause and the large effect. There is the moment when something long held down comes out. There is the turn that cannot be undone. Von Heeren and Koch add that Pholus acts fast and ends fast, with no long drawn-out process.
That is a young body of work, built on a few decades of chart study. Read it as a set of working ideas, not as settled lore. Astrology is not a science, and no one has tested these claims the way a scientist would.
Pholus and Chiron: two centaurs, two tempos
Pholus is best known as a partner to Chiron. Both are centaurs in myth and in the sky. Both have stretched loops, so both move at very uneven speeds through the signs.
The readings differ in tempo. Chiron is read as a slow wound, the sore place you learn to live with and help others heal. Pholus is read as the quick release, the moment a lid comes off. One is a long process. The other is a sudden turn.
The loops differ too. Chiron swings between Saturn and Uranus. Pholus swings much wider, from Saturn out past Neptune. That is why the gaps between signs are so extreme for Pholus. Our guide to Chiron in your chart covers its own timing in detail.
Other centaurs carry other themes. Nessus in astrology tracks harm handed down until someone refuses to pass it on. Hylonome is read for grief.
How to read Pholus in your own chart
Start with the house. The house shows the area of life where a small spark is said to set off a large chain. Pholus in the fourth house points to home and family. In the seventh, it points to close partners. In the tenth, it points to work and public life.
Then look for tight aspects. An aspect is a set angle between two points in the chart, such as a square at 90 degrees or an opposition at 180. Keep the orb small. The orb is how far from exact an angle can be and still count. For a small body like Pholus, two degrees is a sound limit. Contacts with the Sun, Moon, Mercury, Venus or Mars touch daily life most directly.
Last, look at the sign, and weigh it by the table above. A Capricorn Pholus is a generation stamp. A Cancer Pholus is a much rarer mark.
In daily life, the reading turns into a simple habit. Notice where small moments tip into big ones. Pause before you open a lid you cannot close again. When a small event starts a chain, choose your next step with care rather than in haste.
How I measured these numbers
I used the Swiss Ephemeris, a standard set of planet tables, with its asteroid file for Pholus. I found each sign change to the nearest second by halving the search window again and again. I then added up the time between sign changes over ten full loops. A loop runs from one final entry into Aries to the next. All positions are tropical and seen from the centre of Earth.
For a second route, I pulled daily positions from NASA’s JPL Horizons service for 1880 to 2080. Horizons runs its own orbit fit. Every one of the 86 sign changes in that window matched, with the same sign and the same day. The largest gap in time was under two hours, and 68 of the 86 were under one hour. Over eight loops, from 1618 to 2346, the share of time in each sign agreed within 0.02 points between the two routes. I checked the half-return ages the same way, and all six matched.
One limit is worth stating. The orbit of a centaur shifts slowly over the centuries, as the big planets tug on it. My loops ran from 87 to 92 years. The shares above hold for this era. Far in the past or future, they will drift.

Frequently asked questions
What does Pholus mean in astrology?
Modern astrologers read Pholus as the small cause with the large effect. It marks the place in a chart where one small act is said to set off a chain of change. The idea comes from its myth, and from writers of the 1990s.
How long does Pholus stay in one sign?
It depends on the sign. Over ten loops, Pholus spent about 1.9 years per pass in Cancer and about 22.6 years per pass in Capricorn. The current pass through Capricorn runs from January 2018 to November 2042, with wobbles at each end.
What sign is Pholus in right now?
Capricorn. It has been there for good since October 22, 2019, and it will stay until November 2042. It turned direct on September 25, 2026, at 9°53′ Capricorn.
Why do so many people have Pholus in Capricorn?
Because Capricorn is the slow end of its loop. Pholus is farthest from the Sun there, so it moves most slowly. Everyone born from late 2019 to early 2040 shares it.
Is Pholus the same as Chiron?
No. Both are centaurs, but they follow different loops and carry different readings. Chiron is read as a slow wound and its healing. Pholus is read as a sudden release.
Did ancient astrologers use Pholus?
No. Pholus was found in 1992. Ptolemy, Valens and Lilly never knew of it. Its meanings are modern, built from myth and recent chart work.
