9938 Kretlow is a main belt asteroid. It orbits the Sun once every 3.13 years. [cite web|url = http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9938|title = 9938 Kretlow (1988 KA)|work = JPL Small-Body Database Browser | publisher = NASA/JPL | accessdate = 2008-02-19]

Discovered on May 18, 1988 by W. Landgraf at the European Southern Observatory, it was given the provisional designation "1988 KA". It was later renamed "Kretlow" after Mike Kretlow, a student at the University of Siegen who studied comets and a longtime friend of the discoveror of 9938 Kretlow. [MPC 42359 "Minor Planet Center]
