... Earth-Sun distance. Transits occur when the planet passes between the Earth and Sun. NB. Transits of Venus are rare, because the orbit of Venus is inclined to the ecliptic (the plane of the Earth’s orbit) by 3.394 degrees. As Venus passes between Earth and Sun, Venus occults (blocks) the light from ...

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.
