Johannes Kepler's Birth Chart
Sun in Sagittarius · Moon in Libra
Johannes Kepler was a German polymath who was an astronomer, mathematician, astrologer, natural philosopher and music theorist. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copernicanae. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, natural science, and modern science. He has been described as the "father of science fiction" for his novel Somnium. Wikipedia
Section I · The core
The two luminaries
Two lights set the tone of the whole chart: the Sun, the identity; the Moon, the emotional world.
Johannes Kepler's Sun, in Sagittarius
Your identity is an arrow: meaning, horizon, the faith that there's always a wider land.
Johannes Kepler's Moon, in Libra
Your emotional peace depends on the harmony around you: conflict weighs on you, beauty repairs you.
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.
Section III · The detail
Planets and aspects
The exact numbers behind the drawing. Each table expands one layer of the wheel.
Johannes Kepler'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.
| Planet | Sign | Degree |
|---|---|---|
| Sun | Sagittarius | 29°04′ |
| Moon | Libra | 19°15′ |
| Mercury | Sagittarius | 11°26′ |
| Venus | Sagittarius | 28°21′ |
| Mars | Libra | 1°32′ |
| Jupiter | Pisces | 16°12′ |
| Saturn | Scorpio | 12°26′ |
| Uranus | Capricorn | 7°43′ |
| Neptune | Gemini ℞ | 24°17′ |
| Pluto | Pisces | 21°50′ |
Johannes Kepler'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.
Elements and modalities
How their energy is split across the four elements and the three modalities.
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.
Bucket
A group of planets with a single one opposite: that 'handle' planet becomes the channel of the whole chart.
Their energy concentrates in the element of Fire and the Mutable modality.
Sun is the most connected planet in their chart: 5 aspects tie it to the rest.
Three or more planets together in Sagittarius: a strongly marked focus of energy in that area.
An opposition with a third planet square to both: the chart's engine of tension and achievement.
