Takeshi Urata

+ Minor planets discovered: 642 was a Japanese astronomer. He was a prolific discoverer of asteroids, observing at Nihondaira Observatory.

In 1978 he became the first amateur to discover a minor planet (2090 Mizuho) in over fifty years, which he named after his daughter, Mizuho. Urata shared his observation data with peer astronomers in Japan on a periodical called "Tenkai" (the Heavens), as well as contributed to academic journals such as Advances in Space Research and participated in poster presentations at astronomical conferences.

Urata co-discovered the periodic comet 112P/Urata-Niijima in 1986. One of the most active amateur astronomers in Japan, he was also an editor of the Japanese Ephemerides of Minor Planets. The 1927-discovered asteroid 3722 Urata is named after him.
