The essence · Sun

Sun in Capricorn

10°49′

Your centre is mastery: patient ambition, responsibility, maturity and work that supports others. You flourish by taking on your goals with discipline, patience and the determination to build something lasting.

The inner world · Moon

Moon in Taurus

23°44′

Your emotional calm needs solid ground: routines, stability, physical comfort, body, nature and bonds that don't wobble. You nourish and are nourished through simple sensory pleasure, patience and the certainty of what is firm.

The threshold · Ascendant

Birth time not documented

The Ascendant changes sign every two hours, and no verified birth time is recorded for Isaac Asimov, so this chart doesn't set it. Their planets by sign, however, remain reliable.

Section II · The map

Their natal wheel

The sky on the day they were born. The outer ring is the twelve signs; the lines across the centre, the aspects between planets. Without a birth time, houses and the Ascendant aren't drawn.

Isaac Asimov's placements

We compute the placements for the day of birth. Without the exact time the Ascendant and houses can't be fixed, but each planet's sign is reliable.

Beyond the planets

Three keys beyond the ten classical planets, which astrology reads as axes of the chart. All four angles need your birth time.

Chiron2°38 Aries

The wounded healer: a small icy body between Saturn and Uranus. It marks the wound that, once moved through, teaches.

North Node23°55 Scorpio

Not a body but a point of the Moon's orbit. It marks the direction of your growth.

Lilith8°15 Sagittarius

The Black Moon: a mathematical point tied to the untamed and what refuses to submit.

Isaac Asimov's aspects

Each aspect is an angle between two planets; it defines how they speak to each other. Aspects to the Moon are approximate: they depend on the exact birth time.
