3640 Gostin (1985 TR3) is a main-belt asteroid discovered on October 11, 1985, by Shoemaker, C. and Shoemaker, E. at Palomar.

It is named after geologist Victor A. Gostin[2] of the University of Adelaide, who in the 1980s discovered the ejecta layer from the Acraman bolide impact at a distance of 300 km from the impact site, within Ediacaran sedimentary rocks of the Flinders Ranges, South Australia, which enabled the impact to be dated at ~580 Ma.[3]
