Stars
The scientific star names are easy to understand (if you know your Greek alphabet</LINK>. To make star classification simple, they were given Greek letters. For example, 'alpha Ophiuchi' means it is the brightest star in the constellation Ophiuchus. Combined with the genitive, this is known as the 'Bayer designation'. Some stars have proper names as well, for example, alpha Ophiuchi is Rasalhague. Others are known by their catalogue number. Sometimes the cataloguing is a little off, or the stars are variable.
