Hipparchus developed a table of chords and used his trigonometric methods to calculate eclipses of the sun and moon. He also created the first listing of stars, dividing them into classes of brightness, a revised system that is still used by modern astronomers. Hipparchus also was the first individual to define a circle as 360 degrees. Much of his life's work centered around trying to accurately determine the length of a year.
