"The next question was - what makes planets go around the sun? At the time of Kepler some people answered this problem by saying that there were angels behind them beating their wings and pushing the planets around an orbit. As you will see, the answer is not very far from the truth. The only difference is that the angels sit in a different direction and their wings push inward." -Richard Feynman
Hatter Planetarium, built in 1966 with a generous gift from Mr. and Mrs. George G. Hatter, serves the Gettysburg College campus and surrounding community with free programs that explore a variety of astronomy topics. The planetarium is located in the north wing of Masters Hall on the Gettysburg College campus.
The facility is used to illustrate the motions of the heavens to introductory astronomy classes, and with rows of seats circling the room to provide comfortably for one hundred, it's also the location of The Sky this Month and other shows that are open to the community, as well as to members of Gettysburg College; many pre-school, elementary and high school groups visit Hatter Planetarium during the school year for talks and demonstrations on the heavens.
