Named in honor of Dennis L. Matson, planetary scientist at the Jet Propulsion Laboratory, who has played a leading role in developing the method for determination of the sizes and albedos of minor planets by means of infrared radiometry. He has also shown that the heat flow from the interior of Jupiter’s satellite Io can be measured and monitored from ground-based telescopes. (M 6956)
