STAR NAMES WITH CONSTELLATION ENDINGS

Bright stars generally have names preceeded with a Greek letter or Roman
letter(s) and a constellation name.  An example is Alpha Centauri. The 
constellation name is in the latin genitive form meaning "of". Thus Alpha 
Centauri really means Alpha of the constellation Centaurus. Latin grammar is 
a little complicated with five declensions (noun endings) and the singular 
and plural forms. Here are examples of the genitive forms of the constellation 
names:
