17602 Dr. G.           Discovered 1995 Sept. 19 by T. B. Spahr at the Catalina Station of Steward Observatory.
Stephen Gottesman (b. 1939), a radio astronomer at the University of Florida for 35 years, was an advisor to 15 students and a teacher and friend to many others. His research involved galactic structure and dynamics, but his celestial namesake honors the endless enthusiasm and respect "Dr. G." afforded his students.
