Named in memory of Edwin P. Hubble (1889–1953), who provided the first comprehensive exploration of the universe beyond our own galaxy. He established a self-consistent distance scale as far as the 2.5-m Mount Wilson reflector could reach, and his classification scheme for galaxies is still the standard. He discovered the unique minor planet  (1373) Cincinnati. His greatest achievement, however, known as Hubble’s law of redshifts, can be interpreted as observational basis for the expanding universe.
