The asteroid was discovered on October 8, 1999, and was originally known as "Asteroid 1995TR156." It was renamed "24068 Simonsen" for then science teacher Larry Simonsen Jr., who mentored a finalist in the 2007 Discovery Channel Young Scientist Challenge (DCYSC). The DCYSC, a national middle school science competition, chose 40 finalists from state science fair competitions to share their work at the Smithsonian Museum of Natural History in Washington, D.C.
