(5829) Ishidagoro Main-belt Asteroid
Discovered on 11 February 1991 by Otomo, S., Muramatsu, O. at Kiyosato.
Named in memory of Goro Ishida (1924–1992), who was associate director of the Okayama Astrophysical Observatory (a branch of the Tokyo Astronomical Observatory) for over a quarter of a century and contributed much to astronomical research. After retirement he was actively engaged in literary work, notably as president of the Herschel Society of Japan. He also led several study tours sponsored by that society to Europe and South Africa. He was a man of wide tastes and well known as a researcher of kabuki (traditional drama). Named by the discoverers following a suggestion by S. Kimura and T. Ohtani.Naming citation (WGSBN Bull. 4, #12, 4), IAU / Minor Planet Center, via NASA/JPL
