Isaac Asimov’s birth chart
Born 2 January 1920, in Petrovichi, Russia. StarMap has no verified birth time yet.

Isaac Asimov’s zodiac sign and chart, in brief
Isaac Asimov was born on Friday, 2 January 1920, in Petrovichi, Russia. That made Isaac a Capricorn, with the Moon in Taurus. Isaac died on 6 April 1992, aged 72. StarMap has no verified birth time for Isaac, so the chart is cast for midday and leaves the houses out.
By element the count is three fire, three earth, two air and two water. By modality the count is five fixed, three cardinal and two mutable. The tightest aspect is Mars sextile Jupiter, about 0.3° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Four planets were retrograde: Jupiter, Saturn, Neptune and Pluto. The Moon was waxing gibbous, between first quarter and full.
StarMap's dataset holds 12 other people born on 2 January, among them Cuba Gooding Jr., Maxi Rodríguez and Kate Bosworth. Nobuyuki Kato was born on the very same day.

Isaac Asimov’s Sun, Moon and rising sign
Sun sign
Capricorn
about 10° Capricorn at midday
A Capricorn Sun endures. Ambition, patience and a dry sense of humour are what tend to carry Isaac Asimov up long slopes other people give up on. The placement learns, eventually, that rest is part of the climb.
Moon sign
Taurus
in this sign all day; the degree depends on the birth time
A Taurus Moon feels through the body and its surroundings. On this reading, good food, familiar places and slow evenings are what restore Isaac, and sudden change lands hard. Once they feel safe, they can be the steadiest person in the room.
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 Petrovichi, Russia, at each hour of the day.
Isaac Asimov’s rising sign, by birth time
StarMap has not verified a birth time for Isaac 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 2 January 1920, computed for Petrovichi, Russia.

Isaac Asimov’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Isaac Asimov’s private life.
With the Sun in Capricorn, Isaac Asimov is likely to find purpose in building a reputation and a structure that will outlast them, with a vitality that is steady rather than showy. The trap can be measuring their worth by output alone. They may well work through tiredness instead of naming it, until someone else has to point it out.
A Taurus Moon needs routine, familiar food and physical comfort to feel steady from day to day. A sudden change of schedule probably unsettles Isaac more than they let on. A good bed, a favourite mug or the same coffee order can turn an unsteady morning around.
Isaac'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 Isaac 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.
In Isaac's chart, Mars in Libra acts diplomatically and prefers negotiation to confrontation, and its anger tends to stay buried until it is too big to ignore. Avoided consistently, conflict leaves resentment building underneath the calm surface. The pattern is saying yes to something that rankled, then feeling it later.
Jupiter in Leo
16° Leo 53' at midday ℞
growth and excess
Jupiter in Leo grows through creative confidence and a willingness to take up space. For Isaac the overreach may be overselling their own contribution or expecting more credit than a situation calls for. There is a natural showmanship here that lifts a room, and occasionally a story that grows a little in the retelling.
Competence is what Saturn in Virgo builds discipline around, often driven by a fear of not yet having done enough to deserve rest. Isaac may feel like a fraud even when the track record says otherwise. The usual result is someone quietly excellent at something long before they will admit it out loud.
Uranus in Aquarius
29° Aquarius 01' at midday
freedom, generational
Uranus is at home in Aquarius, and many people born in the years around Isaac's birth have it too. The generation is defined by rapid technological and social change within a single lifetime. One person's share of it is an unusually easy relationship with disruption and reinvention.
Neptune in Leo
10° Leo 55' at midday ℞
imagination, generational
Neptune in Leo is the imagination of an age group, not of Isaac alone. It dreams in terms of fame, spectacle and larger-than-life self-expression. The trace of it in one person is a pull towards performance as a way of feeling real.
Pluto in Cancer
6° Cancer 39' at midday ℞
power, generational
Pluto in Cancer dates Isaac to an era rather than describing one person. Those born in it live through deep transformation of family, home and nationhood. What an individual may carry is intensity around belonging and who counts as family.
Aspects in Isaac Asimov’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.
Mars sextile Jupiter
about 0.3° at midday
There is confident, well-aimed energy in this sextile, and not much wasted effort, since Isaac Asimov's drive and optimism pull together. Taking the initiative suits Isaac, above all when they commit to one goal and do not scatter their energy across several.
Sun trine Saturn
about 0.9° at midday
Effort and identity feel like the same project under a Sun-Saturn trine, because Isaac's sense of self and capacity for discipline reinforce each other. What they build tends to last, since ambition and patience are already in agreement.
Venus square Uranus
about 1.4° at midday
In Isaac's chart the desire for closeness and the need for freedom can work against each other, and this square is known for sudden shifts in an otherwise good relationship. The remedy is to build enough independence into the relationship that none has to be created by pulling away.
Sun opposition Pluto
about 4.0° at midday
The Sun opposite Pluto sets plain self-assertion against the draw of power struggles with people who seem to threaten Isaac's sense of control. Working through it leaves Isaac with a strength that has no need to prove itself.
Mercury sextile Mars
about 4.4° at midday
Speaking up quickly and clearly when it matters comes easily to Isaac, since thinking and drive work in step. That plain directness serves them well in fast-moving conversations and quick decisions alike.
Mercury trine Jupiter
about 4.7° at midday
Isaac's thinking and sense of possibility reinforce each other, which gives them an easy, optimistic way of connecting ideas. Learning and explaining come naturally with Mercury trine Jupiter, and a good explanation of theirs tends to stay with people long after the conversation ends.

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?
