Brief definition

Sun signs: (position of the sun at birth)These are the most dominent part about you that you cannot hide. These are what are in magazines. If you are within a few days of the next sign you might share characteristics, this is known as being on the cusp.
Moon sign: (position of the moon at birth) These are your inner emotions and feelings.

To find out where the moon or sun was at your time of birth you should consult an astrologer, but the 12 zodiac signs are written briefly on where they were. Every moon sign also has a stone (which most people already know), a flower and an animal.
