What the chart says

Thomas, according to the stars

How Thomas wants to be loved

Thomas wants to be loved like home. Venus in Cancer needs to feel safe before it feels anything else, and then it feels everything. Remember the small things, meet the family, make the tea. Thomas gives care in a hundred quiet ways and needs to know it is noticed. Consistency is the romance.

How Thomas creates

How Thomas makes things happen: they are the ground everyone else stands on. A Yang Earth day master is the mountain, reliable, slow to move, immovable once it has. Thomas creates by holding: the plan, the people, the standard. They are trusted before they have said a word, and the work is remembering that mountains are allowed to want things too.

Instinct

Instinct: Thomas is larger than life, a Dragon year, and their gut reaction is to go big. Confident, lucky, a natural at the centre of things, and warm-hearted underneath the spectacle. The Metal year sharpens it: principled, determined, clear about what is right.

Purpose

Purpose: Life Path 9 is the humanitarian. Thomas is here for the bigger picture, to give, to finish what others started and hand it on. Wise beyond their years, compassionate, a little world-weary, and learning to receive as freely as they give.

Triggers

Triggers: sloppiness, and being told they are overthinking it. Mars in Virgo means Thomas channels energy into fixing, sorting, getting it right, and gets sharp when others do not care. The critic turns inward first. Give them a problem worth solving and watch them come alive.

Three stars chosen from the real sky above Milwaukee on the night they were born. Choose the story that connects you.

No public birth time is available, so this is a 9:00 p.m. reference evening sky for that date and place. It is connected to the night of birth; it is not the sky at the birth minute, and no other reading on this page uses that time. Dedications are commemorative AsterNym records and do not rename or confer ownership of stars.

The quick version

Leo or Virgo Sun

Thomas A. Steitz was born on a day when the Sun moved from Leo into Virgo. Without a documented birth time, the exact Sun sign cannot be determined reliably, so AsterNym shows both rather than choosing one.

Metal Dragon

Ambition with charisma attached.

Thomas A. Steitz was born on August 23, 1940, which falls in a Metal Dragon year of the Chinese calendar. Traditional Dragon readings emphasise confidence, luck and scale: the only mythical animal in the cycle, associated with ambition and with attention that arrives whether or not it was sought. The Chinese almanacs describe the Dragon as the sign of large gestures. The corresponding caution in the tradition is arrogance, and a difficulty with tasks too small to be seen.

Life Path 9

Compassion at scale.

Thomas A. Steitz's birth date, August 23, 1940, reduces to Life Path 9 under the numerology method AsterNym uses. Traditional Life Path 9 readings associate the number with compassion, generosity and completion: a wide view that takes in more than one person's experience. Numerologists describe it as the path of the humanitarian, the last single digit and the one that closes cycles. The corresponding tension is diffuseness, with the caution that caring about everyone can be easier than showing up for someone.

Reference chart · birth time unknown

No documented birth time exists for Thomas A. Steitz, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 27° to 9° Aries or Taurus 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.

Aspects across every possible birth time

Stable aspects hold for any birth hour. Possible ones depend on the hour, so their orb is a range rather than a number. Orb policy western_v1.

  • stableMoontrineMars0.0° to 6.4° orb

    Thomas’s feelings flow straight into their drive. Effortless, which is exactly why it gets taken for granted.

  • stableMoonsquarePluto0.0° to 6.0° orb

Thomas’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.

  • ChironCancer 26°50′ (moves 0.10° over the day)

    centaur (2060) · the wound and what is learnt from it

    Chiron in Cancer is read as a wound around belonging and being looked after. Thomas is read as someone who learnt to make a home for others before finding one.

  • CeresLibra 11°20′ (moves 0.41° over the day)

    dwarf planet (1) · how a person nurtures and wants to be nurtured

    Ceres in Libra is read as nurture through fairness and company. Thomas is read as someone who feeds others by keeping the peace and the balance.

  • ErosSagittarius 18°18′ (moves 0.23° over the day)

    near-Earth asteroid (433) · what draws them and how they desire

    Eros in Sagittarius is read as desire for the far-off and the free. The reading has Thomas attracted to people who open a door rather than close one.

  • HygieaAries 3°30′ (moves 0.13° over the day)

    main-belt asteroid (10) · health, routine and what keeps them well

    Hygiea in Aries is read as health kept through action and short bursts. The reading has Thomas feeling well when moving and poorly when made to wait.

  • Black Moon LilithAries 8°09′ (moves 0.11° over the day)

    mean lunar apogee · the part that refuses to be tamed

    Black Moon Lilith in Aries is read as the refusal to be second. The modern reading has Thomas carrying an anger that is cleaner than it looks and a need to act on it.

Aspects to the asteroids and Lilith

Major aspects only, at a tight orb. The Moon is left out because its position moves 13° across an untimed day.

  • Hygiea trine Pluto 0.2°
  • Eros trine Mercury 0.4°
  • Chiron sextile Uranus 0.7°
  • Chiron sextile Neptune 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°).

Thomas’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. 1. Mercury8 pts

    rules the Sun sign, Virgo; disposes Sun, Mars, Neptune; 2 major aspects

  2. 2. Venus5 pts

    disposes Jupiter, Saturn, Uranus; 2 major aspects

  3. 3. Sun4 pts

    disposes Mercury, Pluto; 2 major aspects

A Mercury-led chart is read as the mind in charge: Thomas is read as thinking, talking and connecting their way through life.

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 Thomas’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.

  • stellium, the shape it makesStellium in Virgo · Sun, Mars, NeptuneThree or more planets in one sign (four, or three with a luminary, by AsterNym's count): a concentration astrologers read as that sign's themes dominating the chart.

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.

  • Sun semi-square Venus 0.2°
  • Mars semi-sextile Pluto 0.7°

Houses need a birth time. None is documented for Thomas A. Steitz, so no house placements are claimed for the planets or the minor bodies above.

No birth time is on public record for Thomas A. Steitz, so this chart has three pillars rather than four. The hour pillar, the rising sign and the birth-sky star all need a time, and we would rather leave them out than invent one.

Where this data comes from

Thomas’s birth date and birthplace come from Wikidata Q109559, 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.
