(3425) Hurukawa is an asteroid of the main belt that was discovered on January 29, 1929 by the German astronomer Karl Wilhelm Reinmuth at the State Observatory in Heidelberg-Königstuhl ( IAU code 024) near Heidelberg .
The asteroid belongs to the Eos family, a group of asteroids, which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
(3425) Hurukawa was named after the Japanese astronomer Kiichirō Furukawa .
