--(624) Hektor--discovery and notes:

Discovered 10 February 1907 by A. Kopff from Heidelberg. Additional designations 1907 XM, 1948 VD. In 1971 A. F. Cook suggested (624) Hektor was a binary asteroid based on lightcurve observations; it is since understood to be one highly elogated or double-lobed object.

Secondary identified based on observations from the Keck-II adaptive optics telescope on 16 July 2006 by F. Marchis, M. H. Wong, J. Berthier, P. Descamps, D. Hestroffer, F. Vachier, D. Le Mignant, and I. de Pater.
