Kin Endate


Kin Endate is a Japanese amateur astronomer who has discovered hundreds of asteroids, most of them in collaboration with Kazuro Watanabe, placing him among the most prolific discoverers of minor planets.

Career in astronomy

Kin Endate was born in Iwaizumi in Iwate Prefecture and went to Hokkaido Designers School to study photography. He began taking astrophotos in high school, but did not begin serious asteroid observations until 1986.
His notable discoveries include the minor planets 1990 VU1 and 6500 Kodaira, a Jupiter trojan and the Mars-crosser, respectively. He also recorded the first known precovery images of Comet Shoemaker-Levy 9 with his private diameter telescope on March 15, 1993, ten days before the official discovery of the comet. Kin, who was looking specifically for asteroids, did not know of the comet in his images until after the official discovery.

Awards and honors

The main-belt asteroid 4282 Endate, discovered by his colleges Seiji Ueda and Hiroshi Kaneda at Kushiro in 1987, was named in his honor. The official naming citation was published by the Minor Planet Center on 8 July 1990.
