Louis de Broglie’s AsterNym identity

The Steadfast Lightkeeper

Earth represents stability. Earth-led charts are associated with patience, responsibility and the ability to make people or projects feel supported. Life Path 7 represents inquiry: study, solitude and the need to understand what others may simply accept.

What the chart says

Louis, according to the stars

Core essence

Louis is warm the way the sun is warm: not trying, just doing it. The core of Louis is a big open heart and a need to be seen loving with it. They are generous with praise, with time, with the spotlight when they trust you, and they will remember every kindness you paid them for years. Loyal to a fault, and glad of the fault.

How Louis wants to be loved

Louis 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. Louis gives care in a hundred quiet ways and needs to know it is noticed. Consistency is the romance.

How Louis creates

How Louis makes things happen: they make things grow. A Yin Earth day master is the garden soil, generous, nourishing, the reason other people's ideas take root. Louis creates by caring for the thing until it works, and they are often the quiet reason a whole group is thriving. The work is keeping some of that richness for themselves.

Instinct

Instinct: Louis 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 Water year softens it: intuitive, adaptable, feeling their way through people.

Purpose

Purpose: Life Path 7 is the seeker. Louis is here to understand, to go deep rather than wide, to keep a private inner world that most people never see. Thoughtful, intuitive, happiest with time alone, and learning to let the right people in.

Triggers

Triggers: being told "because that's how it's done." Mars in Aquarius fights for the idea, the group, the principle, rarely for themselves. Louis goes cool and distant rather than hot, and then does the surprising thing. Point them at a cause and they will rewrite the rules around it.

Louis de Broglie in 15 seconds

Leo Sun

Pride is the engine.

Louis de Broglie's Sun was in Leo for the whole of August 15, 1892, so no birth time is needed to settle it. Traditional Leo readings associate the sign with warmth, visibility and generosity: a natural claim on attention and a habit of handing it back as encouragement. Astrologers describe it as the fixed fire sign, ruled by the Sun. The corresponding tension is pride, with the classical caution that the need to be seen can crowd out people who would rather not be.

Water Dragon

Ambition with charisma attached.

Louis de Broglie was born on August 15, 1892, which falls in a Water 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 7

Asks the better question.

Louis de Broglie's birth date, August 15, 1892, reduces to Life Path 7 under the numerology method AsterNym uses. Traditional Life Path 7 readings associate the number with inquiry, analysis and solitude: the need to understand what others simply accept. Numerologists describe it as the path of the seeker, reflective and private. The corresponding tension is withdrawal, with the caution that a mind at home in its own company can forget to come out.

Louis’s birth chart

Reference chart · birth time unknown

No documented birth time exists for Louis de Broglie, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 18° to 2° Taurus or Gemini 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.

The working: aspects, Chiron and the asteroids, dominant planets and configurationsshow

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.

  • stableMercurysquareNeptune0.2° to 0.5° orb

    Louis’s mind grinds against their imagination.

  • stableMarstrinePluto0.2° to 0.4° orb

    Louis’s drive flows straight into their depths. A talent so smooth it can go unnoticed.

  • stableMercurysquarePluto0.9° to 1.2° orb

    Louis’s mind grinds against their depths. The friction is lifelong. Worked with, it builds real strength.

  • stableSuntrineJupiter1.4° to 2.4° orb

    Louis’s core identity flows straight into their growth.

  • stableNeptuneconjunctionPluto1.4° orb

    Louis’s imagination and depths act as one. Wherever one goes, the other is already there.

  • stableMarstrineNeptune1.5° to 1.8° orb

    Louis’s drive flows straight into their imagination. Effortless, which is exactly why it gets taken for granted.

    Louis’s mind opens doors for their affections. An easy alliance, and it pays off when it is used.

  • stableJupiteroppositionUranus7.6° orb

Louis’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.

  • ⚷ ChironLeo 22°54′ (moves 0.13° over the day)

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

    Chiron in Leo is read as a sore spot around being seen. The tradition has Louis performing through the doubt rather than waiting for it to lift.

  • ⚳ CeresTaurus 26°18′ (moves 0.22° over the day)

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

    Ceres in Taurus is read as nurture through the physical: food, comfort, a steady presence. Louis is read as someone who shows care by providing.

  • ♡ ErosLibra 3°32′ (moves 0.80° over the day)

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

    Eros in Libra is read as desire for the beautiful and the mutual. Louis is read as someone who wants the pairing itself as much as the person.

  • ⚕ HygieaCancer 22°39′ (moves 0.32° over the day)

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

    Hygiea in Cancer is read as health tied to home, mood and belonging. Louis is read as someone who does not thrive far from a base.

  • ⚸ Black Moon LilithScorpio 4°12′ (moves 0.11° over the day)

    mean lunar apogee · the part that refuses to be tamed

    Black Moon Lilith in Scorpio is read as power the person has stopped apologising for. Louis is read as someone others project onto, and who has learnt to let them.

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.

  • Chiron conjunction Sun 0.2°
  • Black Moon Lilith conjunction Uranus 1.7°
  • Chiron trine Jupiter 2.0°
  • Ceres trine Saturn 2.1°
  • Hygiea square Jupiter 2.3°

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°).

Louis’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

    in its own sign, Virgo; disposes Saturn, Neptune, Pluto; 3 major aspects

  2. 2. ☉ Sun6 pts

    rules the Sun sign, Leo; in its own sign, Leo; 1 major aspect

  3. 3. ♇ Pluto4 pts

    disposes Uranus; 3 major aspects

A Mercury-led chart is read as the mind in charge: Louis 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 Louis’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.

  • Sun quintile Neptune 0.0°
  • Jupiter semi-square Pluto 0.2°
  • Mercury sesquiquadrate Jupiter 0.8°
  • Jupiter semi-square Neptune 1.1°
  • Uranus biquintile Pluto 1.2°
  • Sun quintile Pluto 1.3°
  • Mercury quincunx Mars 1.3°

Houses need a birth time. None is documented for Louis de Broglie, so no house placements are claimed for the planets or the minor bodies above.

No birth time is on public record for Louis de Broglie, 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

Louis’s birth date and birthplace come from Wikidata Q83331, 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.
