(562971) Johannhagen Main-belt Asteroid
Discovered on 23 February 2012 by R. P. Boyle K. Äernis at Mount Graham.
Johann Georg Hagen (1847–1930) was an Austrian-American astronomer and Jesuit priest. He was Director at the Georgetown University Observatory (1888–1906) and the Vatican Observatory (1906–1930). Hagen devised several ingenious experiments at the Vatican to demonstrate the rotation of the Earth, directly confirming the theories of Copernicus and Galileo.Naming citation (WGSBN Bull. 3, #2, 15), IAU / Minor Planet Center, via NASA/JPL
