8197 Mizunohiroshi           Discovered 1993 Nov. 15 by T. Kobayashi at Oizumi.
Hiroshi Mizuno (b. 1951), Okayama Seishin University, is a theoretician on the origin of our solar system. He developed a theory about the formation of thick atmospheres of giant planets, such as Jupiter, with intensive studies on the sudden accretion of gas onto the solid core. This mechanism is called the Mizuno process.
