What the chart says
Robert, according to the stars
Core essence
Robert is the friend who says "let's just go" and means today. The core of Robert is faith that the world is bigger and better than the room they are in, and a restlessness to go and check. They are honest to the point of it being a sport, funny by accident, and impossible to keep small. Freedom is not a preference, it is oxygen.
The vibe
Underneath, Robert needs to be adored a little, and there is nothing wrong with that. The Moon in Leo feels things dramatically and generously and wants them noticed. What Robert needs to feel safe is to be chosen out loud: the compliment said in front of people, the text that says you were thinking of them. They repay it tenfold.
How Robert wants to be loved
Robert wants to be loved seriously. Venus in Capricorn is slow to open and then loyal for life, and it shows love by building: the plan, the future, the thing that lasts. Respect is the romance. Show Robert you are in it for real and the reserve melts into a warmth almost nobody else gets to see.
How Robert creates
How Robert 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. Robert 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: Robert is gentle and diplomatic, a Rabbit year, and their gut reaction is to keep the peace and read the room. Graceful, kind, quietly discerning, and much tougher than the soft manners suggest. The Water year softens it: intuitive, adaptable, feeling their way through people.
Purpose
Purpose: Life Path 3 is the creative. Robert is here to express, to make, to say the thing in a way nobody has said it before. Joy is the work: the writing, the performing, the making people laugh. The lesson is finishing what the spark started.
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. Robert 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.

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
Sagittarius Sun
Sagittarius SunRestless in a good way.
Robert Koch's Sun was in Sagittarius for the whole of December 11, 1843, so no birth time is needed to settle it. Traditional Sagittarius readings associate the sign with distance, belief and candour: travel, big questions and an answer given before it was asked for. Astrologers describe it as the mutable fire sign, ruled by Jupiter, and read it for optimism and appetite. The corresponding tension is overreach, with the classical caution that the horizon is more attractive than the ground underfoot.
Water Rabbit
Water RabbitQuiet luck follows.
Robert Koch was born on December 11, 1843, which falls in a Water Rabbit year of the Chinese calendar. Traditional Rabbit readings emphasise tact, grace and the ability to settle a room without seeming to try. The Chinese almanacs describe the Rabbit as the diplomat of the cycle, alert to subtleties and fond of comfort. The corresponding caution in the tradition is avoidance: the tendency to slip away from a conflict that needed to happen.
Life Path 3
Life Path 3The storyteller at the table.
Robert Koch's birth date, December 11, 1843, reduces to Life Path 3 under the numerology method AsterNym uses. Traditional Life Path 3 readings associate the number with expression: words, humour, performance and making things. Numerologists describe it as the path of the communicator, sociable and quick. The corresponding tension is dispersal, with the caution that many things begun and few finished is the classical pattern the tradition warns this number about.
What stands out in Robert’s chart
- The tightest major aspect in Robert Koch's date-only chart is Mercury trine Pluto, with an orb of under 1°.
- Three planets, Mars, Jupiter and Neptune, sit together in Aquarius, which astrologers call a stellium.
- Robert Koch combines an Earth Day Master in BaZi with a mutable Sun and a Life Path on the emotional plane, the combination AsterNym calls The Steadfast Healer.
Robert’s birth chart
Reference chart · birth time unknown
No documented birth time exists for Robert Koch, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 3° to 17° Leo 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.

Robert’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.
⚷ ChironVirgo 1°13′ (moves 0.01° over the day)
centaur (2060) · the wound and what is learnt from it
Chiron in Virgo is read as a wound around never being good enough. The reading has Robert turning that pressure into craft and an eye for what others miss.
⚳ CeresScorpio 7°51′ (moves 0.41° 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. Robert is read as fierce about the people counted as theirs.
♡ ErosCapricorn 21°28′ (moves 0.57° over the day)
near-Earth asteroid (433) · what draws them and how they desire
Eros in Capricorn is read as desire that respects competence and control. Robert is read as drawn to people who have built something.
⚕ HygieaScorpio 13°08′ (moves 0.40° over the day)
main-belt asteroid (10) · health, routine and what keeps them well
Hygiea in Scorpio is read as health through release and honest reckoning. The tradition has Robert carrying stress in the body until it is named.
⚸ Black Moon LilithTaurus 3°26′ (moves 0.11° over the day)
mean lunar apogee · the part that refuses to be tamed
Black Moon Lilith in Taurus is read as an unbargained appetite: for pleasure, for ownership, for a body that answers to nobody. Robert is read as immovable on those points.
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.
- Eros square Pluto 0.4°
- Ceres sextile Venus 1.7°
- Eros conjunction Saturn 2.3°
- Chiron opposition Mars 2.4°
- Black Moon Lilith trine Venus 2.7°
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°).
Robert’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. ♃ Jupiter10 pts
rules the Sun sign, Sagittarius; disposes Sun, Mercury; 5 major aspects
2. ♄ Saturn5 pts
in its own sign, Capricorn; disposes Venus; 2 major aspects
3. ♆ Neptune5 pts
disposes Uranus; 4 major aspects
A Jupiter-led chart is read as scale and optimism leading: Robert is read as reaching for the bigger version of any plan.
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 Robert’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 Uranus 0.5°
- Jupiter semi-sextile Saturn 0.9°
- Venus semi-square Jupiter 1.7°
- Venus semi-square Neptune 2.0°
Houses need a birth time. None is documented for Robert Koch, so no house placements are claimed for the planets or the minor bodies above.

No birth time is on public record for Robert Koch, 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
Robert’s birth date and birthplace come from Wikidata Q37193, 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.
