What the chart says
Sienna, according to the stars
Core essence
Sienna is playing a longer game than everyone else at the table. The core of Sienna is quiet ambition and a dry, private sense of humour that only their people get to see. They are the one who actually does the thing, and then does not mention it. Underneath the composure is someone who wants very badly to be proud of what they built.
How Sienna wants to be loved
Sienna wants to be loved as a friend first, and then as everything. Venus in Aquarius needs freedom, conversation and a partner who finds their strangeness delightful. Rules and jealousy make them cold; acceptance makes them devoted. Let Sienna be fully themselves and they will never want to be anywhere else.
How Sienna creates
How Sienna makes things happen: they cut to it. A Yang Metal day master is the sword, decisive, principled, allergic to nonsense. Sienna creates by clarifying, by deciding, by being the one who says what the thing actually is. Sharp with themselves first. The work is remembering that not every problem needs a blade.
Instinct
Instinct: Sienna is sharp and confident, a Rooster year, and their gut reaction is to say the true thing out loud. Observant, hardworking, honest, and proud of looking the part. The Metal year sharpens it: principled, determined, clear about what is right.
Purpose
Purpose: Life Path 5 is the free spirit. Sienna is here to explore, to change, to taste everything and report back. Adventure, variety and freedom are not distractions from their purpose, they are it. The lesson is choosing, sometimes, and staying.
Triggers
Triggers: unfairness, and being forced to pick a side. Mars in Libra hates open conflict and will negotiate for hours to avoid it, then dig in absolutely when a principle is at stake. Sienna fights for balance. The lesson is that sometimes the fair thing is to just say no.

If you only read one paragraph
Capricorn Sun
Capricorn SunAmbition wearing a plain coat.
Sienna Miller's Sun was in Capricorn for the whole of December 28, 1981, so no birth time is needed to settle it. Traditional Capricorn readings associate the sign with ambition, structure and the long game: building slowly toward a position that will hold. Astrologers describe it as the cardinal earth sign, ruled by Saturn, and read it for discipline and reserve. The corresponding tension is severity, described in the tradition as a seriousness that can be turned on the self as hard as on the work.
Metal Rooster
Metal RoosterSharp eye, sharper tongue.
Sienna Miller was born on December 28, 1981, which falls in a Metal Rooster year of the Chinese calendar. Traditional Rooster readings emphasise precision, candour and pride in appearance and in work done properly. The Chinese almanacs describe the Rooster as observant and punctual, the sign that notices and says so. The corresponding caution in the tradition is vanity, and a frankness that arrives before anyone asked for it.
Life Path 5
Life Path 5Restless, curious, gone.
Sienna Miller's birth date, December 28, 1981, reduces to Life Path 5 under the numerology method AsterNym uses. Traditional Life Path 5 readings associate the number with freedom, change and variety: movement, new experience and resistance to restrictive routine. Numerologists describe it as the path of the traveller, adaptable and restless. The corresponding tension is instability, with the caution that constant motion can become a way of avoiding commitment to any one direction.
What stands out in Sienna’s chart
- The tightest major aspect in Sienna Miller's date-only chart is Sun square Mars, with an orb of about 1°.
- Three planets, Mars, Saturn and Pluto, sit together in Libra, which astrologers call a stellium.
- Five of the ten planets fall in Cardinal signs, making Cardinal the strongest modality in this chart.
- Sienna Miller combines a Metal Day Master in BaZi with a cardinal Sun and a Life Path on the physical plane, the combination AsterNym calls The Gilded Pioneer.
Sienna’s birth chart
Reference chart · birth time unknown
No documented birth time exists for Sienna Miller, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 26° to 8° Capricorn or Aquarius depending on the hour. The wheel's houses are a solar chart, counted from the Sun's sign, because the Ascendant needs a time.
No birth time, so the houses are a solar chart: the Sun’s sign counts as house 1. A documented time would place them from the Ascendant instead.

Sienna’s Chiron, Ceres, Eros, Hygiea and Lilith
Four minor bodies and the mean lunar apogee, placed in the same tropical zodiac as the planets above. None of these feed the chart signature, the rarity score or any ranking on this site: they are listed for readers who use them. Chiron, Ceres, Eros and Hygiea positions come from JPL Horizons; Black Moon Lilith is the mean apogee, the point most published Lilith tables use. The readings are the modern tradition’s, not AsterNym’s. Without a birth time the degree is the noon value and the day's movement is shown alongside it.
⚷ Chiron ℞Taurus 18°20′ (moves 0.03° over the day)
centaur (2060) · the wound and what is learnt from it
Chiron in Taurus is read as a wound around security and worth. The reading has Sienna building steadiness by hand after finding it could not be assumed.
⚳ CeresScorpio 7°42′ (moves 0.37° over the day)
dwarf planet (1) · how a person nurtures and wants to be nurtured
Ceres in Scorpio is read as nurture that goes all in: loyalty, intensity, a care that does not do halfway. Sienna is read as fierce about the people counted as theirs.
♡ ErosTaurus 13°30′ (moves 0.21° over the day)
near-Earth asteroid (433) · what draws them and how they desire
Eros in Taurus is read as desire through the senses and through time. The reading has Sienna wanting what can be touched, kept and returned to.
⚕ Hygiea ℞Leo 6°10′ (moves 0.14° over the day)
main-belt asteroid (10) · health, routine and what keeps them well
Hygiea in Leo is read as vitality that runs on purpose and recognition. The reading has Sienna at their best with something to be proud of.
⚸ Black Moon LilithSagittarius 10°34′ (moves 0.11° over the day)
mean lunar apogee · the part that refuses to be tamed
Black Moon Lilith in Sagittarius is read as a refusal to be told what to believe. The reading has Sienna leaving any room where the truth is decided in advance.
Aspects to the asteroids and Lilith
Major aspects only, at a tight 3° orb. The Moon is left out because its position moves 13° across an untimed day.
- Hygiea sextile Mars 0.5°
- Hygiea square Jupiter 0.6°
- Ceres sextile Sun 0.8°
- Ceres square Venus 1.0°
- Chiron trine Mercury 1.1°
- Black Moon Lilith sextile Venus 1.9°
- Ceres conjunction Jupiter 2.1°
- Hygiea opposition Venus 2.5°
Method: JPL Horizons heliocentric vectors, 1700–2100, cubic Hermite interpolation; geocentric, true ecliptic of date, tropical; geometric (no light-time or aberration); Lilith = mean lunar apogee (Chapront/Meeus mean perigee + 180°).
Sienna’s dominant planets
Scored from rulerships, dispositors and aspect count. Without a birth time there is no Ascendant or house to score, and the Moon's sign is left out where it could change with the hour.
1. ♄ Saturn8 pts
rules the Sun sign, Capricorn; disposes Sun, Mercury; 3 major aspects
2. ♀ Venus5 pts
disposes Mars, Saturn, Pluto; 2 major aspects
3. ♃ Jupiter4 pts
disposes Uranus, Neptune; 2 major aspects
A Saturn-led chart is read as structure and endurance leading: Sienna is read as someone who builds slowly and keeps what is built.
How the score is built
- Rules the Sun sign, Moon sign or Ascendant sign: 3 points each (traditional co-rulers of Scorpio, Aquarius and Pisces score half).
- Sits in a sign it rules: 2 points.
- Disposes another planet (that planet sits in a sign it rules): 1 point each.
- Angular: 2 points in the first or tenth house, 1 point in the fourth or seventh (timed births only).
- Every major aspect it makes: 1 point.
Dominance scoring is an AsterNym method. Other sites weight differently and can name a different leader for the same chart.
Configurations in Sienna’s chart
Closed shapes among the ten planets under the site’s one aspect-orb policy. The Moon is excluded without a birth time, so a shape that needs it is not claimed.
No stellium, grand trine, T-square, grand cross, yod or kite closes among the planets that can be placed. That is the common case, not a gap.
Minor aspects
semi-sextile 30° (orb 2°), semi-square 45° (orb 2°), quintile 72° (orb 1.5°), sesquiquadrate 135° (orb 2°), biquintile 144° (orb 1.5°), quincunx 150° (orb 2.5°). Pairs already in a major aspect are not repeated. Moon excluded without a birth time.
- Mars semi-sextile Jupiter 0.1°
- Mercury semi-square Uranus 0.3°
- Mercury quintile Jupiter 0.4°
- Venus semi-square Neptune 1.3°
- Sun semi-sextile Venus 1.8°
Houses need a birth time. None is documented for Sienna Miller, so no house placements are claimed for the planets or the minor bodies above.

Where this data comes from
Sienna’s birth date and birthplace come from Wikidata Q193458, released under CC0, as do the occupations, works, teams and awards in the biography above. No documented birth time is available, so this chart is rated X on the Rodden scale, the astrological convention for how well evidenced a birth time is. Time-dependent results use a clearly labelled reference time and should not be read as their exact birth chart. Entries are matched to Wikidata by entity id rather than by name, kept only at day precision, and dropped where sources disagree on the date.
