Minoru Honda (本田 実 Honda Minoru, February 26, 1913 – August 26, 1990) was a Japanese amateur astronomer.
He discovered twelve comets between 1940 and 1968, including the periodic comet 45P/Honda-Mrkos-Pajdušáková.
He was the first to report the very bright V1500 Cygni (Nova Cygni 1975) at magnitude 3.0 on August 29, 1975; it peaked at 2.0, and many hundreds of independent discoveries were subsequently made by others.[1]
The asteroid 3904 Honda is named after him, 8485 Satoru is named after his wife, and 11442 Seijin-Sanso is named after his astronomical observatory.[2]
