Discovered on 12 February 1942 by L. Oterma at Turku.
Named in memory of the Swedish count Per Brahe (1602-1680), who was governor general of Finland. The “count's epoch” was a happy era, with the establishment of Academia Aboensis, the first university in Finland, the construction of various new towns and many schools, and the publication of the first Finnish Bible.Naming citation (MPC 5280), IAU / Minor Planet Center, via NASA/JPL
