Decoding Your Birth Chart: The Big 3 in Astrology
You’ve likely heard about horoscopes and sun signs, but a birth chart? Think of it as your own unique blueprint, a snapshot of the sky at the moment of your birth, personalized just for you. It encapsulates the positions of the planets, the sun, and the moon at the precise moment you took your first breath. Knowing (and understanding) your birth chart gives a much clearer and more accurate picture of who you are compared to surface-level sun sign horoscopes.
In this article, we’re focusing on the trio that set the tone for your astrological narrative, known as the “Big 3 in Astrology” – the sun, moon, and rising signs. In their most basic form: The sun reveals your core identity, the moon delves into your emotional terrain, and the rising sign shapes your first impressions and how others see you.
In recent years, I’ve taken a deep dive into everything astrology. Learning to analyze my birth chart helped me get to know myself and my soul’s purpose on an even deeper level. Deciphering your birth chart might initially feel overwhelming, but understanding your ‘Big 3’ is a great place to start!

Your Moon Sign: Navigating Emotional Tides
Your moon sign can be seen as the emotional navigator of the birth chart, guiding us through the ebbs and flows of emotions.

Who are you, at your core, when no one else is looking? What are your deepest thoughts and desires that play out inside your head?
Your Rising Sign: Ascending First Impressions
Your rising sign (the ascendant) can be seen as your celestial mask. It represents the sign that was rising on the eastern horizon at the exact time of a person’s birth. Your rising sign can shape your first impressions and influence how others perceive you. It’s the outer layer of your astrological identity, the face you present to the Universe.
The sign that your ascendant is in can help you understand the vibes you put out when stepping into the world. Unravelling this layer of your astrological self opens the door to understanding how others perceive and interact with you.

2. First Impressions
Your rising sign can play a major role in first impressions. It reflects the mask that you wear when you first meet others. People may see you through the lens of your rising sign before they actually get to know you on a deeper level.
