The Big Three: Understanding Sun, Moon, and Rising Signs in Your Birth Chart

If you only learn three things about your birth chart, make it these: your Sun, Moon, and Rising signs.

Together, they're called the "Big Three"—and they hold the key to understanding your astrological personality, emotional needs, and how the world perceives you.

What Are the Big Three?

The Big Three are the three most important placements in your natal chart:

☉ Sun Sign — Your Core Identity (WHO you are)
☽ Moon Sign — Your Emotional Nature (WHAT you need)
↑ Rising Sign (Ascendant) — Your Outer Personality (HOW others see you)

Think of it like this:

Sun = Your conscious ego, life purpose, what you're here to become
Moon = Your subconscious emotions, inner world, what you need to feel secure
Rising = Your mask, first impression, how you approach life

These three signs work together to create your unique astrological fingerprint. Understanding them is the foundation of natal chart interpretation.

Your Sun Sign ☉: Your Core Identity

What it represents: Core identity, ego, vitality, life purpose, conscious self

The Sun is Your:
