What You'll Discover

What Is a Natal Chart?

A natal chart is a snapshot of the sky at the exact moment of your birth. It maps every planet's position in the zodiac and shows which astrological house it occupied from your birthplace.

Sun, Moon & Rising

The "big three" describe your core identity (Sun), emotional inner world (Moon), and the mask you present to the world (Ascendant / Rising sign).

10 Planetary Placements

Mercury governs communication, Venus love, Mars drive, Jupiter growth, Saturn discipline, Uranus innovation, Neptune dreams, and Pluto transformation.

12 Houses

Houses represent life areas: identity, money, communication, home, creativity, health, relationships, transformation, philosophy, career, community, and the unconscious.

Calculation Accuracy

Accurate to a few arcminutes · 1800–2200 CE

Astro Precise uses the Western tropical zodiac with geocentric ecliptic longitudes. VSOP87-derived mean orbital elements for the outer planets and a full perturbation series for the Sun and Moon, giving positional accuracy typically within a few arcminutes for dates between 1800–2200 CE. The Ascendant is computed from Local Sidereal Time derived from your exact latitude, longitude, and birth time. House cusps follow the selected system (Equal, Placidus, or Whole Sign).
