(5927) Krogh Main-belt Asteroid
Discovered on 19 April 1938 by W. Dieckvoss at Bergedorf.
American mathematician Fred T. Krogh (b. 1937) developed the accurate, flexible and fast numerical integration algorithm used to track and navigate NASA interplanetary spacecraft since the 1970s. His work is at the core of JPL planetary, asteroid and comet orbit solutions and ephemerides.Naming citation (MPC batch dated 2016-08-18), IAU / Minor Planet Center, via NASA/JPL
