9937 Triceratops is a main belt asteroid. It orbits the Sun once every 3.64 years. [cite web|url = http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9937|title = 9937 Triceratops (1988 DJ2)|work = JPL Small-Body Database Browser | publisher = NASA/JPL | accessdate = 2008-02-19]

Discovered on February 17, 1986 by Eric Elst at the European Southern Observatory, it was given the provisional designation "mp|1986 PN|4". On November 21, 2002 it was renamed "Triceratops" after Triceratops, the genus of herbivorous dinosaurs.
