Discovered over 600 minor planets, including several Trojans and centaurs, and made significant contributions to the field of astronomy.
Tsutomu Seki, a renowned Japanese amateur astronomer, has made a lasting impact in the field of astronomy through his numerous discoveries of minor planets and comets. Specifically, he is celebrated for his visual discoveries of six comets between 1961 and 1970, including the iconic C/1965 S1 Ikeya-Seki comet, also known as the great comet of 1965.
Seki currently serves as the Director of the Geisei Observatory in Kōchi, Japan, and is also in charge of the Comet Section of the Oriental Astronomical Association. His illustrious career is marked by the discovery of numerous asteroids, including 13553 Masaakikoyama and 5209 1989 CW1, a near-Earth Amor asteroid and a Jupiter trojan, respectively.
A testament to Seki's contributions, many of his discoveries are named after famous sites in Kōchi, such as:
In recognition of his outstanding contributions, asteroid 3426 Seki, discovered by Karl Reinmuth at the Heidelberg Observatory in 1932, was named in his honor. The official naming citation was published by the Minor Planet Center on December 16, 1986 (M.P.C. 11443).
Tsutomu Seki's discoveries have not only expanded our understanding of the universe but have also inspired future generations of astronomers. His dedication to the field has paved the way for further research and exploration, cementing his place as a pioneering figure in Japanese astronomy.
Born on November 3, 1930, in Kōchi, Japan, Seki's passion for astronomy has driven his remarkable career. Through his work, he continues to inspire and educate the public about the wonders of the universe.
