Do you know your Moon sign? In astrology, the Moon represents your intuition and memories, as well as the parts of your heart that you keep to yourself but still feel deeply. Your Moon sign—aka the zodiac sign the Moon was in when you were born—also shows your emotional reactions to matters, especially in how you nurture others and yourself.

In relationships, Moon sign compatibility is important because it helps you connect on a deeper, emotional level. Your Sun sign represents your ego, determination, and desires, but your Moon sign signifies your innermost sentiments. When two people's Moon signs align, they can develop a relationship that lasts a lifetime and attain an understanding that’s truly soulful.

If you really click with your partner or your crush but your Sun signs are supposedly "incompatible," take a look at your Moon signs—it could explain so much. Keep reading for everything to know about Moon sign compatibility, and a full guide on what pairs make the best matches.

Your Moon sign adds emotional depth to your birth chart. When two people have compatible Moon signs, they can share similar memories from childhood, and they have a deep connection that transcends time. We look to the Moon sign to check out stability and longevity in partnerships. If the Moon signs are compatible, then two people can form a bond that will withstand the test of time.

Sun sign compatibility doesn’t hold as a flame to Moon sign compatibility. Moon signs dictate our emotions and subconscious responses, while the Sun reflects our egos and is easily seen by others. The Moon is our comfort zone and who we are in private, while the Sun reflects the face the world sees first. This means that when it comes to compatibility, it's all about the Moon.
