(140038) Kurushima Main-belt Asteroid
Discovered on 18 September 2001 by A. Nakamura at Kuma Kogen.
Kurushima Kaikyo is a 4-kilometer-wide strait between the islands of Shikoku and Oshima. The strait is notorious among seamen for its rapid tidal currents and complicated submarine topography. In 1999 three long-span suspension bridges were constructed over the strait.Naming citation (20100130/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
