Isaac Asimov
Born on 2 January 1920 in Petrovichi. Without a public birth time, no rising sign: here is what the date and place can calculate.
You and Isaac Asimov
What you are trying to become
You aim far, and you demand a lot of yourself. What you make, you want still standing in ten years. Credit, you give yourself late.
Capricorn begins at the December solstice, the day the Sun turns back. Its symbol is a sea goat: half mountain, half ocean. Saturn rules it.
People think you feel nothing. You have simply already planned next year.
Why?
What you are trying to become, and what you need to be recognised for. In Capricorn, it gets built and proven. You aim far, demand a lot of yourself, and give yourself credit late.
What draws you
What draws you has a secret. Lightness bores you fast: you need someone who holds your gaze and does not lie.
The brightest star of the constellation is Antares: the rival of Mars. Mars rules this sign in the old astrology, Pluto in the new.
Venus is in detriment in this sign. You give all or nothing, and you do not forget who betrayed you.
Why?
What draws you in and what you offer — in love as in taste. In Scorpio, it plays out fully and in private. You watch for a long time before committing, then you do not let go. Opposite its home: adverse ground. What it governs takes deliberate effort — and is worth working for exactly that reason.
What gets you moving
You hesitate to strike first. You weigh, you consult, you look for the way out that upsets nobody. But faced with an injustice, you stand up.
Libra is the only sign of the zodiac that isn’t a living thing: it is an instrument. It weighs, and it stops only when both pans are level.
Mars is in detriment in this sign. You fight your battles better for other people.
Why?
What you go after, and how you fight when you meet resistance. In Libra, it is measured against the other person. You adjust to whoever is across from you, until your own position blurs. Opposite its home: adverse ground. What it governs takes deliberate effort — and is worth working for exactly that reason.
How you think
You think wide. You see the general meaning before the details, and you prefer a big idea to a small proof.
The centre of our galaxy lies in the direction of Sagittarius: look toward the archer, and you are looking at the heart of the Milky Way. Jupiter, the largest planet, rules this sign.
Mercury is in detriment in this sign: you say what you believe before you have checked.
Why?
How you think and speak — the pace, the level of detail, what you keep to yourself. In Sagittarius, it needs a horizon. You take badly to having your ground narrowed, and you leave rather than negotiate. Opposite its home: adverse ground. What it governs takes deliberate effort — and is worth working for exactly that reason.
