(58164) Reiwanohoshi Main-belt Asteroid
Discovered on 20 November 1989 by T. Seki at Geisei.
Following the April 2019 abdication of Japan's Heisei Emperor, the new Reiwa Era began. As ‘‘Reiwa'' means peace and harmony, “Reiwanohoshi” (“the star of Reiwa”) is named to symbolize Japan going into a new peaceful era, free of natural disasters.Naming citation (WGSBN Bull. 1, #1, 19), IAU / Minor Planet Center, via NASA/JPL
