Capricornus Constellation

Capricornus (Pronounciation:Cap-re-corn-us, Abbrev:Cap, Latin:Capricorni) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Capricornus takes up 413.947 sq. degrees of the night sky which equates to 1% of the night sky. The constellation gets its name as it name means The Sea Goat . 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.

Capricornus 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. Capricornus is an equatorial constellation that can be seen by countries nearest the Equator.

The brightest star in Capricornus is Deneb Algedi. There are 6 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site.

Legend of the Constellation

Usually referred to as Amalthea, the goat that suckled the infant Zeus when his mother Rhea saved her son from Cronos, his father. Another story has Pan, the goat god who was attacked by Typhon, the sea monster. Pan dived into the water, the lower part turned into a fish but the top part remained a goat.

Meteor Showers

There are 15 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.

As there's so many stars in the cosmos, not all the stars are listed here.

The stars that I do list have either a traditional name, a bayer or other classification name.
