What Are Sun, Moon, and Rising Signs

In astrology, your Sun, Moon, and Rising signs are known as your Big Three. They are calculated from your birth date, exact birth time, and birthplace, and each represents a different part of your astrological profile. The Sun sign is determined by the Sun's position at your birth, the Moon sign by the Moon's position, and the Rising sign (Ascendant) by the zodiac sign rising on the eastern horizon. Unlike your Sun sign, which is commonly determined by your birthday alone, finding your Moon and Rising signs requires more precise birth information.

Why your Sun, Moon & Rising Sign matters

Your Sun, Moon, and Rising signs reveal a much deeper picture of who you are than your zodiac Sun sign alone.
