When we talk about our star signs, we almost always talk exclusively about our primary sign - our Sun sign. It's the a sign defined by the position of the Sun at the time we were born, and the one which most of us will most closely identify with.

But there is so much more to who we are. We are each influenced by all the elements of our astrological charts including our planets and houses. Our core personality, while often very defined by our Sun signs, is actually made up of three key factors: our Sun sign, our Rising (or Ascendant) and our Moon sign. And arguably, our Moon signs have a lot more to tell us about ourselves that any other aspect of our charts.

What is a Moon sign?

Our Moon sign is an extremely significant aspect of who we are, but it is something that is often glossed over in horoscopes and astrology. Consider Sun and Moon signs as two sides of the same coin. While your Sun sign is the personality you project outwards, your Moon sign is about who you are when you're alone and the way you see yourself. It's a reflection of your inner self.

Your Moon sign is dictated by the position of the Moon when you were born. It's easy to find out. Put your date of birth into Co-Star, it will tell you what you want to know.

What does your Moon sign say about you?

Since your Moon sign dictates your inner self, it has a huge influence on your emotions and subconscious. This means that your love language and what you need from a relationship (romantic and otherwise) are heavily influenced by this element of your chart.

If your Moon falls in an Air sign, Gemini, Libra and Aquarius, then you're more likely to be an extrovert. These are signs of communication, the talkers of the zodiac. You'll be someone that loves a chat, often feels energised by talking in depth and adores socialising.

For those with a Moon in a Water sign, Cancer, Scorpio and Pisces, your inner self will be more sensitive than you let on. Whatever you may project on the outside, you are someone that is naturally intuitive and easily hurt.

A Fire Moon sign, Leo, Aries and Sagittarius, will see themselves as outgoing and spontaneous. While this may not be the energy that everyone gets to see, you will be generous with your emotions and open to new experiences in a relationship.

As for the Earth Moon signs, Virgo, Capricorn and Taurus, you are practical at your very core. When you're alone, you'll take solace in organising the things around you, whether that be ticking off life admin or simply tidying. You'll also be someone that takes great comfort from nature. Emotional turmoil can be cured by the sun and the sea.
