5892 Milesdavis           Discovered 1981 Dec. 23 at the Purple Mountain Observatory.
The distinctive sound of trumpeter Miles Dewey Davis (1926-1991) transcended the bebop era and moved into cool jazz, culminating with So What and the masterly 1959 Kind of Blue album with John Coltrane and Bill Evans.
