World is 2 rarest zodiac sign according to astrology 

All 12 zodiac signs have unique qualities and are special in their own way (they even have corresponding tarot cards and health associations). Being the rarest is special. 

There are some zodiac signs that are more common than others, based on common birthdates, which also affects zodiac trends. 

Zodiac signs are not only common, but there are also rare ones-and one zodiac sign in particular happens to be the rarest of them all.

A Aquarius sun sign is "one of the rarest zodiac signs," says Stardust. Also called "innovators and originators."

Aquarius compatibility with other air signs is based on Stardust's observation. Due to their ability to communicate and think, Gemini and Libra are most compatible with Aquarius.
