What the chart says
Marc, according to the stars
Core essence
Marc feels the room before entering it. The core of Marc is care, the practical kind that remembers what you said in March and has already made the tea. They protect their people with a fierceness that surprises anyone who only knew the soft exterior. Home is not a place for Marc, it is whoever they have decided to keep.
How Marc wants to be loved
Marc 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. Marc gives care in a hundred quiet ways and needs to know it is noticed. Consistency is the romance.
How Marc creates
How Marc makes things happen: they find the gap and grow through it. A Yin Wood day master is the vine, flexible, quietly relentless, better at working around a wall than at knocking it down. Marc creates by adapting, by connecting people, by making the awkward thing fit. Underestimate them and you will look up one day to find them everywhere.
Instinct
Instinct: Marc is warm and generous, a Pig year, and their gut reaction is to trust. Big-hearted, fun, sincere, a lover of good things, and deserving of people who are as honest as they are. The Metal year sharpens it: principled, determined, clear about what is right.
Purpose
Purpose: Life Path 7 is the seeker. Marc 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. Marc 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.

If you only read one paragraph
Cancer Sun
Cancer SunFeeds you before you ask.
Marc Andreessen's Sun was in Cancer for the whole of July 9, 1971, so no birth time is needed to settle it. Traditional Cancer readings associate the sign with protectiveness, memory and attention to the emotional temperature of a room. Astrologers describe it as the cardinal water sign, ruled by the Moon, and read it for loyalty to family and home. The corresponding tension is guardedness: the tradition describes a sign that looks after others more readily than it lets itself be looked after.
Metal Pig
Metal PigAssumes the best. Usually right.
Marc Andreessen was born on July 9, 1971, which falls in a Metal Pig year of the Chinese calendar. Traditional Pig readings emphasise generosity, sincerity and an appetite for the good things, shared. The Chinese almanacs describe the Pig as the most open-handed sign in the cycle, trusting and hard to anger. The corresponding caution in the tradition is naivety, and a difficulty believing that anyone would take advantage of that trust.
Life Path 7
Life Path 7Digs under every answer.
Marc Andreessen's birth date, July 9, 1971, 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.
What stands out in Marc’s chart

Marc’s birth chart
Reference chart · birth time unknown
No documented birth time exists for Marc Andreessen, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 26° to 10° 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.

Marc’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.
⚷ ChironAries 13°50′ (moves 0.01° over the day)
centaur (2060) · the wound and what is learnt from it
Chiron in Aries is read as a sore spot around asserting oneself: Marc may have learnt early that going first costs something, and built a way of leading that does not need permission.
⚳ CeresCancer 1°19′ (moves 0.42° over the day)
dwarf planet (1) · how a person nurtures and wants to be nurtured
Ceres in Cancer sits in the sign the tradition links to it most closely: care as instinct. Marc is read as someone for whom looking after others is not a decision.
♡ ErosCancer 21°02′ (moves 0.92° over the day)
near-Earth asteroid (433) · what draws them and how they desire
Eros in Cancer is read as desire bound up with safety and memory. Marc is read as drawn to people who feel like somewhere to come back to.
⚕ HygieaLeo 26°28′ (moves 0.34° 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 Marc at their best with something to be proud of.
⚸ Black Moon LilithLibra 4°27′ (moves 0.11° over the day)
mean lunar apogee · the part that refuses to be tamed
Black Moon Lilith in Libra is read as the part of Marc that will not keep the peace at the price of the self. Fairness, on these terms, is not the same as niceness.
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 square Jupiter 0.5°
- Black Moon Lilith square Venus 1.0°
- Black Moon Lilith sextile Mercury 1.5°
- Ceres conjunction Venus 2.1°
- Black Moon Lilith trine Saturn 2.1°
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°).
Marc’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. ☽ Moon5 pts
rules the Sun sign, Cancer; disposes Sun, Venus
2. ☿ Mercury5 pts
disposes Saturn, Pluto; 3 major aspects
3. ♃ Jupiter5 pts
disposes Neptune; 4 major aspects
A Moon-led chart is read as feeling first: Marc is read as steered by mood, memory and what feels safe.
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 Marc’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 semi-square Saturn 0.5°
- Venus biquintile Jupiter 0.5°
- Mars biquintile Pluto 0.7°
- Sun biquintile Mars 0.9°
- Venus semi-sextile Saturn 1.0°
- Sun sesquiquadrate Neptune 1.2°
Houses need a birth time. None is documented for Marc Andreessen, so no house placements are claimed for the planets or the minor bodies above.

Where this data comes from
Marc’s birth date and birthplace come from Wikidata Q62882, 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.
