Asteroid 4746, Doi, was discovered on October 9, 1989 by Atsushi Takahashi and Kazuo Watanabe at Kitami Observatory in Kitami, Hokkaido, Japan. It has a period of 5 years, 282 days.
It was named for Japanese aerospace engineer, amateur astronomer and astronaut Takao Doi (born 1954), who flew on two NASA shuttle missions, STS-87 on the Columbia in 1997 in which he became the first Japanese to conduct a spacewalk, and STS-123 on the Endeavour in 2008.
The meaning of asteroid Doi seems to be: to attain something, get back something, rite of passage, initiation, sex, humiliation.
The glyph for Doi is my own conception and is the Japanese characters for Doi's surname.
