50428 Alexanderdessler           Discovered 2000 Feb. 27 by the Catalina Sky Survey.
Alexander Dessler (b. 1928) is a space physicist who shaped understanding of how charged particles interact with magnetic fields of solar system objects. He first defined the existence and characteristics of the heliosphere, confirmed when Voyager 1 crossed the heliopause.
