Mayim Bialik’s zodiac sign and chart, in brief
Mayim Bialik was born in San Diego, California, on 12 December 1975, a Friday. Their zodiac sign is Sagittarius, with the Moon in Aries. Mayim turns 51 in 2026. No verified birth time is on file for Mayim; the chart is cast for midday, without houses.
By element the count is six fire, two air, two water and no earth. Across cardinal, fixed and mutable signs the split is three, three and four. Sagittarius holds a stellium, three planets in one sign: Sun, Mercury and Neptune. Closest of the aspects is the sextile between Neptune and Pluto, about 0.4° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Mars and Saturn were retrograde. The Moon was waxing gibbous, between first quarter and full.

Mayim Bialik’s Sun, Moon and rising sign
Sun sign
Sagittarius
about 20° Sagittarius at midday
A Sagittarius Sun seeks. Meaning, distance and the bigger picture are likely to pull Mayim Bialik forward, and the honesty of this placement is a kind of generosity. Its lesson is that the journey also needs somewhere to land.
Moon sign
Aries
in this sign all day; the degree depends on the birth time
With the Moon in Aries, Mayim is likely to feel fast and forgive fast. Anger comes up quickly and passes just as quickly, and feeling needs a physical outlet. This is a Moon soothed by action, not by talking it over.
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 San Diego, California, at each hour of the day.
Mayim Bialik’s rising sign, by birth time

Mayim Bialik’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Mayim Bialik’s private life.
Growth, travel and ideas bigger than daily life are where Mayim Bialik's Sagittarius Sun finds purpose, and their energy tends to lift the moment there is somewhere new to go. Familiarity is what wears on this placement. A few months into any routine, however good it is, restlessness usually sets in.
The Moon in Aries keeps day-to-day needs simple: something to do right now, and permission to feel it and move on. For Mayim, comfort probably comes from action rather than discussion. The instinct of this Moon is to pace the room or go for a walk rather than sit with a feeling until it passes on its own.
Mayim's Mercury in Sagittarius thinks in big, connective leaps and communicates with enthusiasm and a wide frame of reference drawn from everywhere they have been. The weak point is generalising past what the details support. A specific question may get a sweeping theory nobody quite asked for.
Venus in Scorpio loves intensely and privately, and Mayim is likely to value depth and total honesty over ease. Testing loyalty can create the very distance this placement fears most. There is an all-or-nothing quality to how this Venus commits, with little interest in anything in between.
With Mars in Gemini, Mayim is likely to act through words, argument and quick manoeuvring rather than force, and anger to come out sharp and verbal. Arguments can be won without the conflict underneath ever being resolved. A disagreement can still be under debate long after the other person just wants it to end.
Jupiter in Aries
14° Aries 45' at midday
growth and excess
Jupiter in Aries grows through bold, direct action and taking the first step before feeling fully ready. Mayim's overreach, on this reading, is starting more than can realistically be finished. A burst of confidence tends to get a new venture off the ground, whether or not the groundwork is in place.
Saturn in Leo builds discipline around self-expression, and in Mayim's chart this placement often starts with a fear of being laughed at or overlooked. The doubt tends to show as playing down achievements before anyone else can. The confidence this placement builds is hard-won and unshowy, and it tends to arrive once the waiting for permission stops.
Uranus in Scorpio
5° Scorpio 33' at midday
freedom, generational
Much of Mayim's age group has Uranus in Scorpio. It changes attitudes to power, secrecy and what is held in common, often while living through upheavals in institutions once considered permanent. In an individual it tends to be a low tolerance for hidden agendas.
Neptune in Sagittarius
11° Sagittarius 49' at midday
imagination, generational
Neptune in Sagittarius is the dream of a generation: grand systems of belief and utopian journeys. What belongs to Mayim in it may be a hopeful conviction that the right philosophy will resolve a practical problem.
Pluto in Libra
11° Libra 24' at midday
power, generational
Pluto in Libra is the signature of the generation Mayim 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 Mayim Bialik’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.
Venus conjunction Uranus
about 1.2° at midday
Affection runs independent and a little unpredictable with Venus conjunct Uranus, and Mayim Bialik is likely to be drawn to people and situations that keep them interested more than settled. There is romantic excitement in that. The difficulty is letting closeness deepen without the urge to bolt from it.
Jupiter trine Neptune
about 2.9° at midday
Optimism and imagination tend to flow together for Mayim, and what comes of it is an inspired, generous vision of what is possible. Hope and creativity tend to serve them well under this trine, especially when both are allowed to guide a project and neither is second-guessed.
Saturn square Uranus
about 3.3° at midday
The need for stability and the need for freedom can clash in Mayim's chart, producing either rigid routines that eventually snap or sudden breaks from commitments that were meant sincerely. Saturn square Uranus is best answered with structure loose enough to bend before it has to break.
Jupiter opposition Pluto
about 3.4° at midday
In this opposition, the urge to expand outward meets a need to control the process so tightly that it limits the very growth being sought. When Mayim loosens their grip on the outcome, the opportunity itself tends to get through.
Mercury opposition Mars
about 3.9° at midday
Mayim is likely to hold a point of view firmly and, with Mercury opposite Mars, to argue it harder than the moment calls for. Listening as actively as they argue resolves more than winning the point does.
Sun opposition Mars
about 3.9° at midday
The Sun opposite Mars pits self-assertion against putting other people's wishes first, and for Mayim that can play out as a tug of war with partners or rivals. Learning to want things directly, without needing a fight to justify the wanting, settles more than it stirs up.
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?
