(4725) Milone Main-belt Asteroid

Discovered on 31 December 1975 by Felix Aguilar Observatory at El Leoncito.

Named in honor of Luis Ambrosio Milone (b. 1933), Argentinean astronomer who has been working in the field of stellar astrophysics for more than 30 years. Since 1964 he has been on the faculty of the School of Mathematics, Astronomy and Physics of the National University of Cordoba, where he teaches graduate and post-graduate courses in astronomy and astrophysics. Milone was responsible for building a photoelectric photometer for the Bosque Alegre Observatory 1.5-m telescope. He was the initiator of photoelectric photometry in Cordoba and one of the first astronomers to apply these techniques.Naming citation (19990202/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
