The essence · Sun

Sun in Cancer

4°44′

Your core is care and protection: memory, shelter and the ability to make a home anywhere. Your life purpose is nourished by belonging, care and emotional memory. Your strength lies in welcoming, protecting and creating spaces where sensitivity is valued.

The inner world · Moon

Moon in Gemini

28°06′

Your emotions ask for words: to name them, tell them, understand them in conversation. You process what you feel through thought and speech. Your emotional security comes from understanding your experiences, voicing them and keeping your mind open and flexible.

Birth time not documented

The Ascendant changes sign every two hours, and no verified birth time is recorded for William Thomson, 1st Baron Kelvin, 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.

The exact numbers behind the drawing. Each table expands one layer of the wheel.

William Thomson, 1st Baron Kelvin'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.

Chiron17°26 Aries

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

North Node9°30 Capricorn

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

Lilith21°41 Aquarius

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

William Thomson, 1st Baron Kelvin'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.

Section IV · The signature

The signature of their sky

The whole at a glance: how the planets are spread, and the accents that set the overall tone of the chart.

Chart shape

Bucket

A group of planets with a single one opposite: that 'handle' planet becomes the channel of the whole chart.

Dominants

Their energy concentrates in the element of Air and the Cardinal modality.

Traits

Mars is the most connected planet in their chart: 8 aspects tie it to the rest.
