Facts About 13 Common Zodiac Constellations You May Not Know

First off, what exactly is a constellation? A constellation is a group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure. Modern astronomers have actually divided the sky into 88 constellations with defined boundaries. Out of the 88 recognized constellations, 13 are zodiac constellations. There are about 21 Zodiacal constellations total, but only 13 official Zodiac signs.
