Sergey Brin’s birth chart
Born 21 August 1973, in Moscow, Russia. StarMap has no verified birth time yet.
Leo Sun · Moon in Taurus or Gemini
Sergey Brin’s zodiac sign and chart, in brief
Sergey Brin was born on Tuesday, 21 August 1973, in Moscow, Russia. That makes Sergey a Leo. The Moon left Taurus for Gemini at about 16:25 local time, which leaves the Moon sign open without a birth time. Sergey turns 53 in 2026. StarMap has no verified birth time for Sergey, so the chart is cast for midday and leaves the houses out.
Air carries the most weight: four of the nine planets whose sign does not depend on the birth time, against fire three, earth one and water one. Across cardinal, fixed and mutable signs the split is four, four and one. Venus, Uranus and Pluto all fall in Libra. No two planets sit closer to an exact angle than Jupiter and Neptune: a sextile, about 0.1° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Jupiter was retrograde. The Moon was at its last quarter.
StarMap's dataset holds 18 other people born on 21 August, among them Robert Lewandowski, Mohammed VI of Morocco and Stephen Hillenburg.

Sergey Brin’s Sun, Moon and rising sign
Sun sign
Leo
about 28° Leo at midday
A Leo Sun shines. For Sergey Brin that suggests warmth, generosity and a need to be seen for who they really are, running through much of what they do. This placement grows by learning that the light is not diminished when it is shared.
Moon sign
Taurus or Gemini
Taurus until about 16:25, then Gemini (local time). Which one depends on a birth time StarMap does not have.
Born before about 16:25: Moon in Taurus
A Taurus Moon feels through the body and its surroundings. On this reading, good food, familiar places and slow evenings are what restore Sergey, and sudden change lands hard. Once they feel safe, they can be the steadiest person in the room.
Born after about 16:25: Moon in Gemini
The Moon in Gemini processes feeling by naming it. For Sergey, talking, writing and switching perspective are likely ways to settle, and silence can make small worries loud. They probably need people who let them think out loud.
Rising sign
The rising sign changes about every two hours, so it cannot be known without a birth time. The table below shows which sign was rising over Moscow, Russia, at each hour of the day.
Sergey Brin’s rising sign, by birth time
StarMap has not verified a birth time for Sergey yet. It shows a birth time only when Astro-Databank rates it AA, A or B on the Rodden scale (AA from a birth certificate or record, A from the person, someone close to them or a news report, B from a biography). Until then, this is the rising sign for every possible time of birth on 21 August 1973, computed for Moscow, Russia.
| Born around (local time) | Rising sign |
|---|---|
| 00:00 to 02:30 | Cancer rising |
| 02:30 to 05:30 | Leo rising |
| 05:30 to 08:30 | Virgo rising |
| 08:30 to 11:35 | Libra rising |
| 11:35 to 14:35 | Scorpio rising |
| 14:35 to 17:10 | Sagittarius rising |
| 17:10 to 18:50 | Capricorn rising |
| 18:50 to 19:50 | Aquarius rising |
| 19:50 to 20:30 | Pisces rising |
| 20:30 to 21:15 | Aries rising |
| 21:15 to 22:10 | Taurus rising |
| 22:10 to 23:50 | Gemini rising |
| 23:50 to 24:00 | Cancer rising |
Times are rounded to five minutes. Close to a boundary, a few minutes either way change the answer.

Sergey Brin’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Sergey Brin’s private life.
Purpose for Sergey Brin is probably tied to creating and being seen doing it, and a Leo Sun's vitality rises the moment there is an audience, even an audience of one. The tension is losing steam when no one is watching. The giveaway is often the extra effort that goes into something the moment someone notices them making it.

Taurus until about 16:25, then Gemini
needs and habits
Born before about 16:25: Moon in Taurus
A Taurus Moon needs routine, familiar food and physical comfort to feel steady from day to day. A sudden change of schedule probably unsettles Sergey more than they let on. A good bed, a favourite mug or the same coffee order can turn an unsteady morning around.
Born after about 16:25: Moon in Gemini
The Moon in Gemini runs its daily habits on conversation and mental stimulation, and Sergey is likely to settle by talking a worry through rather than sitting with it quietly. A day with no one to talk to can leave them restless. The habit is to message a friend the moment something comes to mind, before deciding what to think about it.
Mercury in Leo gives Sergey a mind that thinks in confident, story-shaped terms and communicates with warmth and a bit of flair, drawing people in even when the subject is dry. Attachment to being right can make Sergey more persuasive than accurate. A simple update, in their hands, can become something closer to a performance.
Venus in Libra loves with an instinct for balance and partnership, and Sergey probably values harmony, fairness and someone who makes an effort to look good together. The risk with this Venus is staying in a relationship for the sake of the pairing itself. Sergey may give up a personal preference before anyone has even asked.
Mars in Taurus acts deliberately and sticks with a course once chosen, and its anger builds slowly but takes a long time to cool once it arrives. At times Sergey may dig in out of stubbornness rather than conviction. It takes real provocation to make this Mars snap, and the rattled feeling tends to last a while afterwards.
Jupiter in Aquarius
4° Aquarius 31' at midday ℞
growth and excess
Jupiter in Aquarius grows through community, ideas and causes bigger than one life. Sergey may put so much trust in a theory or a group that its practical flaws are overlooked. Optimism about the future can make them a natural organiser of other people's efforts.
Emotional security is where Sergey's Saturn in Cancer builds discipline; it is a placement often associated with learning early to be the steady one. Asking for care tends to be difficult with this Saturn, even when care is clearly needed. Over time, people with this placement often become the dependable anchor for others, including some who never quite return the favour.
Uranus in Libra
20° Libra 13' at midday
freedom, generational
Sergey holds Uranus in Libra in common with many people born in the same stretch of years. Together that generation reshapes ideas of partnership, fairness and how relationships are arranged. Its personal side is a readiness to question traditional roles more openly than earlier generations felt able to.
Neptune in Sagittarius
4° Sagittarius 40' at midday
imagination, generational
Neptune in Sagittarius is the dream of a generation: grand systems of belief and utopian journeys. What belongs to Sergey in it may be a hopeful conviction that the right philosophy will resolve a practical problem.
Pluto in Libra
2° Libra 56' at midday
power, generational
Pluto in Libra is the signature of the generation Sergey belongs to, because Pluto moves so slowly. That generation transforms ideas of partnership, fairness and what people owe one another. Personally it can be an intense need for relationships to be fundamentally fair.
Aspects in Sergey Brin’s chart
How the planets stand to each other, tightest first. Without a birth time the orbs are those at midday, and aspects to the Moon are left out because the Moon moves about thirteen degrees in a day.
Jupiter sextile Neptune
about 0.1° at midday
Inspired ideas are within Sergey Brin's reach without any loss of footing, since possibility and imagination are gently linked by this sextile. The optimism is soft and workable, useful for keeping a project hopeful without letting it drift far from what is real.
Venus conjunction Pluto
about 0.2° at midday
Love tends to run deep and complete under Venus conjunct Pluto, and Sergey is likely to lean towards intensity over casual affection. Relationships gain depth from it. What takes practice is trusting a connection without needing to test it to prove it is real.
Venus square Saturn
about 0.8° at midday
Venus square Saturn can pair the desire for closeness with a fear of not being quite enough to keep it. For Sergey that may mean self-doubt in relationships that have given no reason for it, and the fear can ease each time they let themselves be loved without first having to deserve it.
Saturn square Pluto
about 1.0° at midday
Saturn square Pluto sets the need for control against the instinct for transformation, and Sergey may grip a structure most tightly at the very moment it needs to change. Each old form that is let go leaves a strength behind that is more real than the grip was.
Mars square Jupiter
about 1.0° at midday
Drive can outrun capacity under Mars square Jupiter, and Sergey may overextend on a project or on a promise made in a burst of confidence. The enthusiasm is sound. It needs matching to a pace that can be sustained.
Mars sextile Saturn
about 1.5° at midday
Sustained effort feels manageable, not draining, when Mars and Saturn are in sextile, and Sergey has that combination of drive and discipline. What results is quiet, dependable follow-through, the kind that gets a long project finished while flashier approaches give out halfway.
The rest, listed without a reading. Those between Uranus, Neptune and Pluto hold for years at a time, so everyone born while one holds shares it.

How this page is made
Planet positions are computed with the astronomy-engine ephemeris and checked against Swiss Ephemeris. Birth dates and places come from Wikidata; birth times, where StarMap has one, come from Astro-Databank and are shown with their Rodden rating. The readings describe what a placement is traditionally taken to mean. They are written by StarMap for reflection and entertainment, not as statements about the person’s private life. New to charts?
