Elizabeth and Philip Synastry at a Glance
Queen Elizabeth II and Prince Philip’s synastry has 30 contacts between the two charts, close to the 31.1 average of two random people. What stands out is how tight a few of them are: three are within one degree, and both Moons are in Leo.
Both birth times on this page come from published sources, so the synastry includes the Ascendants and every house-based point. That makes this one of only two famous couples on the site whose charts can be read in full.
Elizabeth was born with the Sun at Taurus 0°13′ and a Capricorn Ascendant; Philip with the Sun at Gemini 18°53′ and a Leo Ascendant. The bi-wheel above draws her chart inside his.
How to read the contact list
Each contact in their synastry is listed with its orb, how far it is from exact, and with its base rate, the share of 1,000 random pairs that have the same contact. The orb says how strong a contact is; the base rate says how unusual it is.
What the numbers do not say
A tight contact is not a reason a marriage lasted. The same synastry contacts appear in relationships that ended quickly, and nothing here explains anyone’s choices.
Two Leo Moons, Three Degrees Apart
Elizabeth’s Moon is at Leo 12°07′ and Philip’s at Leo 15°08′. In synastry, a Moon–Moon conjunction is read as two people who need the same things to feel settled.
What a Moon–Moon contact describes
Astrologers read the Moon as habits, comfort and the way a person recovers from a hard day. When two Moons share a sign, those rhythms are read as familiar to each other.
Leo in particular
A Leo Moon is read as needing warmth, loyalty and a sense of occasion. It is a fitting placement for two people whose lives were lived in public, though astrology cannot say whether it shaped those lives.
How rare it is
Only 5.6% of random pairs have a Moon–Moon conjunction, which makes it the least common of their eight tightest contacts. At 3.01°, it is also wider than the three contacts below; the Moon conjunct Moon page reads the contact in depth.
Her Moon on His Neptune
Elizabeth’s Moon sits 0.51° from Philip’s Neptune at Leo 11°37′. In synastry, Neptune on the Moon is read as idealism and sensitivity between two people.
Idealism and duty
Neptune contacts are read as seeing the other person through a softer light. With the Moon involved, the focus is on feelings and care rather than romance.
The base rate
9.2% of random pairs share a Moon–Neptune conjunction, so it is distinctive without being rare.
Read without hindsight
It is easy to match a contact to a known story after the fact. The honest reading is narrower: this synastry contact describes a tone, and what two people make of a tone is not in the chart.
Pluto on Mercury: The Tightest Contact
The tightest contact in their synastry is Elizabeth’s Pluto at Cancer 12°42′ conjunct Philip’s Mercury at Cancer 13°03′, 0.34° from exact.
What Pluto–Mercury is read as
Mercury is how a person thinks and speaks; Pluto is depth and intensity. The site’s synastry library reads this contact as two currents that fuse and are hard to separate.
Why generational planets count here
Pluto moves slowly, so many people born around 1926 share Elizabeth’s Pluto. What makes it personal is the partner’s Mercury landing on it.
How common it is
9.4% of random pairs have a Pluto–Mercury conjunction. The contact is common; its tightness is not.
Her Mars Opposite His Ascendant
Elizabeth’s Mars at Aquarius 20°52′ opposes Philip’s Ascendant at Leo 18°39′, 2.22° from exact. Only 7.0% of random pairs have this contact.
Energy across the horizon
An opposition to the Ascendant falls on the other person’s Descendant, the point astrologers link with partnership. Mars there is read as drive and directness aimed at the partner.
Why the birth times matter here
This contact exists only because both birth times are known. With a date-only chart for either of them, it would not be drawn at all.
A second angle contact
Her Ascendant at Capricorn 21°25′ is also 3.09° from a trine to his Saturn, read as steadiness between them. 18.9% of random pairs share that synastry contact.
The Composite Chart: Sun and Mercury in Taurus
Their composite chart, made of the midpoints of each pair of planets, has the Sun at Taurus 24°33′ and Mercury beside it, 0.69° away. The composite Ascendant is at Taurus 5°02′.
A Taurus composite
Taurus is read as steadiness, patience and attachment to what has been built. In a composite chart it describes the relationship’s own temperament rather than either person’s.
The composite Moon
The composite Moon is at Leo 13°38′, between their two natal Moons. Two Moons in the same sign give a composite Moon in that sign too.
The tightest composite aspects
Composite Venus at Aries 9°40′ squares composite Pluto, 0.65° from exact, and composite Mars opposes Saturn within 1.19°. Both are read as intensity and pressure inside a lasting bond.
The Davison Chart: 15 November 1923, Over Northern Italy
Their Davison chart is cast for 15 November 1923 at 04:50 UT, halfway in time between June 1921 and April 1926. The place is halfway between London and Corfu, near Pontoglio in Lombardy.
A Scorpio Sun opposite the composite
The Davison Sun is at Scorpio 21°48′, 177° from the composite Sun in Taurus. The two Suns face each other whenever the births are an odd number of years apart, counted to the nearest year: here 4.9 years, so five.
Moon and Ascendant
The Davison Moon is at Aquarius 19°24′, a waxing crescent, and the Davison Ascendant is at Scorpio 4°20′.
Its tightest aspects
The Davison Sun is conjunct Mercury within 0.48°, echoing the composite’s Sun–Mercury pair. Mercury squares Neptune within 0.95°, and the Moon opposes Neptune within 0.97°.
How Much of Their Synastry Depends on the Birth Times
Because both times are known, this synastry can be recast without them to see what a date-only version would have shown. The comparison is a good lesson in reading any famous couple’s chart.
Seven contacts disappear
Cast both charts for noon and the synastry drops from 30 contacts to 23. Every contact with an Ascendant goes, including her Mars opposite his Ascendant and her Ascendant trine his Saturn.
The Moons move
At noon both Moons sit near Leo 16°, so the Moon–Moon conjunction would look almost exact, 0.37°. With the real times it is 3.01°.
Her Moon on his Neptune
The opposite happens to her Moon on his Neptune: 0.51° with the real times, but 5.1° in the noon charts. A date-only synastry can make one contact look tighter and another wider than it is.
Where Their Birth Times Come From
Their synastry can be read in full only because both birth times are documented. Here is where each one comes from.
Elizabeth: The Times, 1926
The Times of 22 April 1926 reported that the Duchess of York “gave birth to a daughter at No. 17, Bruton-street at 2.40 yesterday morning”. Britain was already on summer time that week, so the chart uses 02:40 BST.
Philip: two biographies
Philip Eade’s Young Prince Philip (2011) writes: “At 10 a.m., a baby boy was delivered.” Denis Judd’s 1980 biography quotes the Greek registration with the same hour.
The older times
A 1972 source gave 21:46, and a nanny remembered that “the sun was setting”. Both conflict with the registration, so this page uses 10:00.
The Greek calendar
Greece still used the Julian calendar in 1921, so his registration reads 28 May. The chart uses the Gregorian date, 10 June 1921.
Seventy-Three Years of Marriage, and What Charts Cannot Say
They first met as children in 1934, at a royal wedding, and met again at Dartmouth in 1939. Their engagement was announced on 9 July 1947 and they married at Westminster Abbey on 20 November 1947.
The public record
Philip died on 9 April 2021, after 73 years of marriage. Elizabeth died on 8 September 2022.
What the synastry adds, and what it does not
The synastry describes a pair of charts with several tight contacts and two Leo Moons. It does not explain a seventy-three-year marriage, and it would not have predicted one.
