What are the Signs of the Zodiac?
The Zodiac is an astronomical division of the sky through which the apparent paths of the sun, moon, and major planets all pass. The zodiac is considered to have 12 segments, each covering 30°, and each of which is named for a constellation, groups of stars that have acquired names in the Greco-Roman tradition, often of animals and mythological characters. Note that there are other cultural traditions of constellations that are not part of this system. For example, there are Native American, African, Hawaiian, Australian aborigine, and Arab constellations.
