Named in honor of Eberhard Grün (1942– ), a physicist at the Max-Planck-Institut für Kernphysik, Heidelberg. Starting with the Helios missions, Grün has been responsible for dust collectors on a number of interplanetary spacecraft, including Giotto, Ulysses, Galileo and Cassini. He has also interpreted the data collected and determined the dynamical properties of dust particles. In addition to his research activities, Grün is a professor at the University of Heidelberg, where he passes on to students his knowledge and long experience in space missions. (M 27458) _ _.
