9844 Otani (1989 WF1) is a main-belt asteroid discovered on November 23, 1989 by Yoshio Kushida and Osamu Muramatsu at the Yatsugatake South Base Observatory. It was named in honor of Toyokazu Otani (1928- ), first lecturer at the Gotoh Planetarium and Astronomical Museum in Tokyo, where he worked for 32 years until 1988[1]. His deep knowledge of acoustics and classical music was instrumental in establishing the well-known BMG sound system, appreciated by planetarium audiences. Otani is also known as an eminent observer of the planets[2].
