... The constellations of the zodiac appear at different times to the ‘Star Signs’ due to a factor called PRECESSION – caused by the axis of the Earth having a slightly off-centre motion, like the wobble of a spinning top toy. The precession occurs over about a 26,000 year cycle, meaning that the North ...

History of astronomy
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World (see astrology and astronomy). In some cultures, astronomical data was used for astrological prognostication.Ancient astronomers were able to differentiate between stars and planets, as stars remain relatively fixed over the centuries while planets will move an appreciable amount during a comparatively short time.
