5617 Emelyanenko           Discovered 1989 Mar. 5 by E. F. Helin at Palomar.
Vyacheslav Emelyanenko (b. 1952), head of the department of theoretical mechanics at South Ural University, has made a lifetime study of celestial mechanics, with major contributions to understanding the dynamical evolution of comets, minor planets and meteoroid streams. The name was suggested by M. Bailey.
