37645 Chebarkul           Discovered 1994 Feb. 8 by E. W. Elst at the European Southern Observatory.
On 2013 February 15 a small asteroid exploded above the city of Chelyabinsk. A large fragment continued its voyage to the city of Chebarkul, where it penetrated the surface of a neighboring lake, creating a 8-meter diameter hole.
