The large fraction of transneptunian objects that are binary or multiple, 48 such systems are now known, has been an unanticipated windfall. Separations and relative magnitudes measured in discovery images give important information on the statistical properties of the binary population that can be related to competing models of binary formation. Orbits, derived for 13 systems, provide a determination of the system mass. Masses can be ","authors_text":"Eugene I. Chiang, Jean-Luc Margot, Keith S. Noll, Susan D. Kern, William M.
