Andromeda Constellation

Andromeda (Pronounciation:An-drom-e-da, Abbrev:And, Latin:Andromedae) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Andromeda takes up 722.278 sq. degrees of the night sky which equates to 1.75% of the night sky. The constellation gets its name as it name means Ethiopian Princess . 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.

Andromeda is a northern hemispheric constellation which means it can't be seen easily or at all from the southern hemisphere. The brightest star in Andromeda is Mirach. There are 8 Extrasolar Planets (Exoplanets) detailed on this site.

Legend of Andromeda

Andromeda was the daughter of Queen Cassiopeia and King Cepheus, rulers of the kingdom of Philistia. The kingdom is now more closely associated with Ethiopia. The Queen was so jealous of her daughter`s looks that she had her tied to a large rock. The Queen hoped the whale, Cetus, would kill her. She was saved by Perseus who then became his bride. The story is immortalised in the film `Clash of the Titans

Andromeda Galaxy

The galaxy boasts one of our closest neighbouring galaxy, M31, Andromeda Galaxy. Our Galaxy, the milky way is reckoned to be 100,000 light years across but the Andromeda Galaxy is twice the size. It is expected to collide with our galaxy but don`t worry, it won`t happen for another 5 billion years at least. When it does, no one on Earth will be around to see it. All life on Earth will have gone after the sun has grown large and heated the Sun. It is not the nearest galaxy to us, the Canis Major Dwarf Galaxy takes that title. The Andromeda Galaxy has been to shown to have planets in orbit round some of its star. The galaxy is the furthest object in space that one can see with the naked eye. You won`t be able to see the galaxy in much detail but you`ll be able to see it as a fuzzy patch.

Alpheratz

The star Alpheratz (Alpha Andromedae) is the brightest star in the constellation and also forms one corner of the square in Pegasus. It is sometimes referred to as Delta Pegasi to note its location.

Meteor Showers

There are 11 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.
