Summary: Stellar Distances
... The proper motion of a star, µ , is the annual rate at which its location (direction) on the celestial sphere changes. (This is in addition to the annual parallactic motion.) It is usually expressed in seconds-of-arc per year. Tangential velocities are obtained by measuring both a star’s proper moti ...

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.
