Sagittarius (Pronounciation:Sadge-e-tar-e-us, Abbrev:Sgr) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Sagittarius takes up 867.432 sq. degrees of the night sky which equates to 2.1% of the night sky. The constellation gets its name as it name means Half-Man/Half-Horse Archer . 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.
Sagittarius is a member constellation of the Zodiac grouping, a group of 12 star signs that astrologers use to predict someones future based on their date of birth and which constellation appeared when the Sun set. The Zodiac year may be divided up equally between the twelve signs but when they appear in the night sky no longer conforms to the Zodiac calendar. Sagittarius is an equatorial constellation that can be seen by countries nearest the Equator. The brightest star in Sagittarius is Kaus Australis. There are 10 Extrasolar Planets (Exoplanets) detailed on this site.
He was known as Crotus, son of Pan, a Centaur. A centaur is a half-man, half-horse. Commonly mistaken for Chrion who is immortalised as Centaurus . He was the protector of Muses where he invented applause. The Muses asked Zeus when he died to turn him into a constellation as a reward for his dedication.
The centre of the milky way, a giant black hole is located within this constellation. It is located near the border with Scorpius. There are a number of very large supergiant stars in this constellation, them being KW and VX Sagittarriis.
There are 13 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.
