Sun Signs Astrologyis a form of astrology mostly found in many newspaper and magazine columns. It is also known as Newspaper Astrology. It is a simplified system of astrology which considers only the position of the Sun. The Sun is said to be placed within one of the twelve Sun Signs depending on the month of birth. Thus, this sign is called the Sun Sign or Star Sign of the person born in that month.

Sun Signs Astrologers take this as a basic twelve-fold division and relate all the current movements of all the planets to each other, using traditional rules to relate meanings for each sign separately. Moon is often used as the main indicator of daily trends for Sun Sign Astrology forecasts because the Moon has the fastest apparent movement of all the heavenly bodies.

Despite its vast popularity with the general public there is much argument about the validity of ,Sun Sign Astrology, particularly amongst astrologers of different persuasions. The more traditional the astrologer, the more likely they are to dislike Sun Sign Astrology.

Although William Lilly in the 17th century was the first newspaper astrologer, Sun Signs Astrology was not invented until 1930. The astrologer R. H. Naylor was claimed by his newspaper to have predicted the crash of the R101 airship. This led to pressure on Naylor to come up with a simplified system of astrology suitable for a newspaper column. After some experimentation, Naylor decided on sun signs.

Owing to the popularity of horoscope columns in many newspapers and magazines, it is often erroneously believed that Sun Signs Astrology is the whole extent of astrology. Still many of Horoscopic astrologers view these predictions as highly generalized and of little value.
