Born: June 21, 1982, 9:03 PM local time, Paddington, London, England. Source: Astro-Databank, Rodden rating AA.
The AA rating means the birth time comes from an official record, so the rising sign, the Midheaven and the houses below can be read with confidence. Open Prince William's chart on Astrolas alongside this read.
Four of the ten planets in this chart sit in the 9th house: Mars and Saturn in jLibra, Pluto also in Libra, and YJupiter in Scorpio. The Astrolas library ties the 9th house to higher study, long travel, law and belief, the part of a chart built around a wider view of the world, a fitting engine for a man whose adult life has run through university, military flying, and a role spent representing his country abroad.
A second, quieter cluster sits close behind it. The Sun and Moon meet in fCancer, both in the 7th house of partnership, which the library ties to marriage and close bonds. The chart reads less like someone pulled outward for its own sake, more like someone who takes the wider world seriously because he has a fixed, private center to return to.
Four planets in the 9th house
Mars sits at 9ยฐ12' Libra and Saturn at 15ยฐ30' Libra, both direct; Pluto, retrograde, sits further along at 24ยฐ10' Libra; Jupiter, also retrograde, sits apart in sign at 0ยฐ29' Scorpio but shares the house.
The library's Mars in Libra puts energy into relationships rather than solo pushes, with a charm that rarely takes the first step; in the 9th house it reads as an adventurous spirit with intense faith in personal ideals, rewarded by travel and higher education so long as it doesn't tip into stubbornness. Saturn in Libra sharpens judgment and fairness, suiting mediation, diplomacy, law or the arts, and tends toward marrying later, to someone mature; in the 9th house that discipline lands on belief and education, arriving later than most but on firmer ground. Pluto in Libra is generational, shared by everyone born between 1971 and 1984, a cohort that came of age alongside the end of the Vietnam War and the Watergate scandal; retrograde in the 9th, the library reads it as higher study pursued for private reasons, with beliefs rebuilt from the inside before being carried outward. Jupiter in Scorpio brings willpower and sharp instincts with resources; retrograde here, the library describes curiosity that goes deep rather than wide, knowledge passed on quietly rather than broadcast.
William studied geography at St Andrews, graduating in 2005, and has spent much of his public career on tours representing the country abroad. In 2020 he founded the Earthshot Prize, a global environmental award built on a council of outside experts rather than one public face, which suits a 9th house running on shared conviction more than personal spotlight.
Sun conjunct Moon in Cancer, in the 7th house
The Sun sits at 0ยฐ06' Cancer and the Moon at 4ยฐ58' Cancer, conjunct with an orb of 4ยฐ52', both in the 7th house.
The library's Cancer Sun is sensitive and intuitive, strong in loyalty and care, prone to retreat when hurt. Its Cancer Moon, in the sign the library calls the Moon's natural home, runs deeper still: devoted, quiet about its feelings, wanting a dependable home. The 7th house doubles down on both, tying identity to one close relationship rather than solo achievement, and emotional steadiness to partnership, with most people in this position wanting both a life partner and children. The conjunction itself, read as a birth close to the New Moon, fuses will and feeling into one steady, focused drive, with stubbornness as its main risk.
William met Catherine Middleton at St Andrews in 2001 and married her a decade later, in April 2011, at Westminster Abbey. They have three children: Prince George (2013), Princess Charlotte (2015) and Prince Louis (2018). A long run-up to marriage, and a public life built heavily around that one relationship, both sit easily inside a Sun-Moon pair this tightly bound to the 7th house.
Mercury in Gemini and Venus in Taurus, both in the 5th house
Mercury sits at 8ยฐ58' Gemini and Venus at 25ยฐ40' Taurus, both in the 5th house, which the library ties to creativity, romance and children.
The library's Gemini Mercury is quick, curious and built for communication. In the 5th house that curiosity shows up as play: real enjoyment in games and intellectual challenge, genuine pleasure talking and playing with children rather than just supervising them. Venus in Taurus is warm and loyal, slow to commit but steady once it does, valuing comfort and shared security; in the 5th house the library adds natural magnetism and an eye for beauty, affection shown through small, chosen gestures.
William was President of the Football Association from 2006 to 2024, when he stepped back into a scaled-down patron's role, and has long supported Aston Villa. He's also been photographed often playing football and rugby with his children, a habit that fits a 5th house built around games shared with the people closest to him. The chart's two tightest contacts overall run through this part of the sky too, Mercury trine Mars at 0ยฐ14' and Sun trine Jupiter at 0ยฐ23', though the library has no text for either; treat them only as fast wiring into the Libra-Scorpio group.
Neptune conjunct the Ascendant
The Ascendant sits at 27ยฐ26' Sagittarius. The library doesn't yet have an entry for a Sagittarius rising on its own, so this section leans on the tightest aspect reaching it: ONeptune at 25ยฐ33' Sagittarius, retrograde in the 12th house, conjunct the Ascendant with an orb of 1ยฐ53'.
Neptune in Sagittarius by sign is generational, tied by the library to a search for meaning and a pull toward other cultures. The conjunction to the Ascendant makes it personal: a mysteriously alluring presence that blends into almost any setting, with a caution that it's easy to be drawn in by other people's charm, so the advice is to stay a little skeptical and lean on real financial and legal advice rather than instinct alone.
William grew up inside one of the most photographed families in the world, and the intense media attention that followed his mother, Diana, Princess of Wales, after her death in a car crash in Paris in 1997, shaped how carefully his public image has been handled since. A rising sign that adapts easily to any room, paired with a stated need to guard against being taken advantage of, both track with a public figure whose private life is managed with unusual care.
Jupiter conjunct the Midheaven
Jupiter sits at 0ยฐ29' Scorpio, retrograde, in the 9th house. The Midheaven sits at 2ยฐ26' Scorpio, in the 10th house of career and public standing, conjunct with an orb of 1ยฐ56'.
The library has no separate entry for a Scorpio Midheaven, so this section rests on the conjunction, read as a strong marker for career success and a prosperous family together, built on real luck but needing hard work to match it, with a caution against letting ambition crowd out home life.
William trained as a search-and-rescue helicopter pilot with the RAF, then flew for the East Anglian Air Ambulance until 2017, before moving into royal duties full time. He became Prince of Wales in September 2022, after his father acceded to the throne as King Charles III, a path from military service into a public role carrying status and family expectation together, which fits a Jupiter-Midheaven conjunction built on exactly that mix.
Uranus in the 11th house
IUranus sits at 1ยฐ30' Sagittarius, retrograde, in the 11th house of groups and friendships. By sign, Uranus in Sagittarius marks a whole generation's reach for freedom and new thinking rather than anything personal to William; the house is where it becomes his own.
The library's retrograde Uranus in the 11th describes someone who stands out among friends while keeping some distance, connecting deeply with only a few on the same wavelength, while still caring about group causes and humanitarian work. New ideas form quietly on the inside before they're shared; reform tends to fix a system from within rather than break it in public.
The Earthshot Prize fits that pattern again, a project run through a council of outside figures rather than one face. William has also kept a notably small, stable circle of friends since school, in line with that quiet approach to groups.
What the chart adds up to
The chart doesn't explain duty, or settle what it means to be heir to a throne. What it shows is where the weight sits: four planets crowded into the 9th house pointed outward toward education, travel and belief, balanced against a Cancer Sun and Moon locked together in the 7th house of partnership.
