Naming

This minor planet was named for a donated farm near Helsinki, where various institutes have established their observing stations: the Finnish Geodetic Institute for space geodesy, the University of Helsinki for astrophysics, and the Helsinki University of Technology for radio astronomy. (Also see Metsähovi Radio Observatory). The approved naming citation was published by the Minor Planet Center on 26 May 1983 (M.P.C. 7946).
