How rare is it to be an earth zodiac? And is there such thing as sun and moon signs?
Being born under an Earth zodiac sign (Taurus, Virgo, Capricorn) is not particularly rare, as one fourth of the zodiac signs are Earth signs. It is actually quite common to have an Earth element dominate in one's birth chart.
As for sun and moon signs, these are two of the most widely known components of astrology. Your sun sign represents your core personality traits, while your moon sign represents your emotional inner world. Both are important factors in your astrological profile and can influence different aspects of your life.
