A natal chart is a snapshot of the sky at your birth, computed astronomically (AstroOrbi uses Swiss Ephemeris — the same data professional astrologers rely on). It looks overwhelming, but the reading order is well established.
Step 1: the Big Three
- Sun — the core: what fuels you and what you're building.
- Moon — emotional needs: what makes you feel safe. More in our Moon sign guide and the Moon in all 12 signs.
- Rising sign — your interface and first impression; it requires an exact birth time — here's how to find yours.
Step 2: personal planets in signs
Next come Mercury (thinking and speech), Venus (love and values), Mars (action and anger). The sign shows how the planet operates: Mars in Aries acts head-on, Mars in Libra negotiates. For outer planets, start by checking their houses only.
Step 3: houses
Houses are twelve life spheres, from self-presentation (1st) to career (10th) and the subconscious (12th). A planet's house shows where its story unfolds: Venus in the 10th charms a career, in the 4th — a home. An empty house isn't an empty sphere; the sign on its cusp describes it.
Step 4: aspects
Aspects are angles between planets: conjunctions and trines blend energies easily, squares and oppositions create the friction that drives growth. As a beginner, check the major aspects to your Sun, Moon and Rising — those are the loudest storylines.

FAQ
Can I build a chart without my birth time?
Yes, partially: Sun, planets in signs and an approximate Moon remain, but the Rising sign and exact houses need the time. Birth records usually have it.
How is this different from a magazine horoscope?
A magazine horoscope sorts everyone into 12 groups by Sun sign. A natal chart is an individual astronomical calculation — two identical charts are practically impossible.
