(5584) Izenberg Main-belt Asteroid
Discovered on 31 May 1989 by H. E. Holt at Palomar.
Named in honor of Noam Izenberg (b. 1967), planetary scientist at the Applied Physics Laboratory of Johns Hopkins University and an expert in the geologic interpretation of reflectance spectra. Izenberg played a major role during the NEAR mission to (433) Eros through accurate calibration of the Near-Infrared Spectrometer and through a careful analysis of the data returned.
