We wish to look at some of the players in our historical journey. There is much more information available about these people than will be set down upon these pages. Any one of them would make a good extra credit project or term paper. I will stick to brief descriptions of their major contributions to astronomy. All dates are approximate. I only want you to get a general feel for when they were prominent.
Aristotle & Aristarchus
Eratosthenes & Hipparchus
Copernicus, Brahe, & Kepler
Galileo & Newton
