128065 Bartbenjamin, provisional designation 2003 OK, is an asteroid from the outer asteroid belt that discovered by Bert L. Stevens at Desert Moon Observatory on 19 July 2003. It measures 3.5 kilometers in diameter, but is irregularly shaped. In March 2008, it was named in honor of Bart Benjamin, Director of the Cernan Earth and Space Center of Triton College in River Grove, Illinois, former curator at the Lakeview Museum of Arts and Sciences in Peoria, Illinois, and longstanding member of the Peoria Astronomical Society.


After joining the Peoria (Illinois) Astronomical Society, Bart Benjamin (b. 1958) became a curator at the Lakeview Museum of Arts and Sciences in Peoria, making astronomy exciting for the public. He eventually became director of the Cernan Earth and Space Center at Triton College in west suburban Chicago.[1]
