Ask an astrologer where to begin and they’ll say the same thing: your Big Three. Your Sun, your Moon and your rising sign are the headline of your whole chart.
Most people know their Sun sign. The Big Three adds two more placements that change the picture completely, and together they explain why no two people of the same sign are ever quite alike.
Your Sun: who you are
The Sun is your core identity, your vitality and the direction you’re growing toward. It’s the “I am” of your chart, and the sign almost everyone means when they ask “what’s your sign?”.
Your Moon: how you feel
The Moon moves fastest of all the bodies, and it rules your inner world: your feelings, your needs and what makes you feel safe. Two people with the same Sun but different Moons can feel like different creatures underneath.
Your rising: how you meet the world
Your rising sign, or ascendant, is the sign that was climbing over the eastern horizon at the exact minute you were born. It sets where your chart begins and colours the first impression you give. Because it changes every couple of hours, this is the placement that really needs your birth time.
