In approximately 300 BC , with the help of Aristillus , he created the first Star Catalogue in the Western world. (His worked was predated by that of the Chinese astronmer Gan De .) Over 150 years later, Hipparchus would compare his own star catalogue to Timocharis' and discover that the Longitude of the stars had changed over time, which led him to determine the first value of the Precession Of The Equinoxes . The Timocharis Crater on the Moon is named in his honor. EXTERNAL LINKS
