It was discovered on 15 March 1993, by Japanese amateur astronomers Kin Endate and Kazuro Watanabe at Kitami Observatory in eastern Hokkaidō, Japan.
[11] In October 2014, a rotational lightcurve of Kodaira was obtained from photometric observations by American astronomer Robert Stephens at the Center for Solar System Studies (U81) in California.
Lightcurve analysis gave a well-defined rotation period of 5.400 hours with a brightness variation of 0.78 magnitude (U=3).
[6][7][9] According to first-year results from the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Kodaira measures 9.5 kilometers in diameter and its surface has an albedo of 0.15,[5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 16.8 kilometers with an absolute magnitude of 12.6.
[4] This minor planet was named after Keiichi Kodaira (born 1937), Japanese astronomer and director of NAOJ, whose interests lie in astrophysics and galactic physics.
