Ophiuchus Constellation

Ophiuchus (Pronounciation:Off-you-cuss, Abbrev:Oph, Latin:Ophiuchi) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Ophiuchus takes up 948.34 sq. degrees of the night sky which equates to 2.3% of the night sky. The constellation gets its name as it name means The Serpent Holder . The constellation is one of the original constellations that was devised by the Ancient Greco-Egyptian astronomer Ptolemy who lived between 90 A.D. and 168 A.D.

Ophiuchus is an equatorial constellation that can be seen by countries nearest the Equator. The brightest star in Ophiuchus is Rasalhague. There are 12 Extrasolar Planets (Exoplanets) detailed on this site.

To some people, Ophiuchus is the thirteenth sign of the Zodiac because the sun sets in this constellation during the year. Most astrologers will discount Ophiuchus but there are some that do recognise and produce horoscopes for this constellation. If you`re born at the end of November or beginning of December, its likely your real star sign will be Ophiuchus and will explain why your horoscope forecast is always wrong. As Ophiuchus is inserted, other constellations will move too. For more information, have a look at my other Ophiuchus page.

Legend of the Constellation

Whilst Apollo was away, Coronis was unfaithful to him and bore a son Asclepius with Ischys. When Apollo found out, he killed his wife and removed the baby. The baby Asclepius was given to the Centaur Chiron who taught him medicine. He was able to raise people from the dead which angered Hades. The Underworld God, Hades asked Zeus to put an end to this and Asclepius was struck down by a thunderbolt. Asclepius created his medicines from the poisons of plants and snakes. After death, Asclepius became the constellation Ophiuchus. This constellation is sometimes referred to as the thirteenth star sign, the one that Astrologers ignore.

There are no major meteor showers that radiate from within this constellation.
