The Oakley Observatory is a teaching observatory with eight permanently mounted telescopes. One of the telescopes is a six-inch refractor built by Clark and Sons in 1886. The other telescopes are all reflecting telescopes ranging in size from eight to twenty two inches. In addition to being used for astronomy classes students use the observatory for research and recreation. Several minor planets have been discovered at Rose-Hulman, most notably numerous discoveries by American astronomer Chris Wolfe(also see Category:Discoveries by Chris Wolfe).
