BINARY MINOR PLANETS V4.0

The data set lists orbital and physical properties for well-observed or suspected binary/multiple minor planets including the Pluto system, as inspired by Richardson and Walsh (2006) and similar reviews (Merline et al., 2003; Noll, 2006; Pravec et al., 2006; Pravec and Harris, 2007; Descamps and Marchis, 2008; Noll et al., 2008; Walsh, 2009). In total 202 companions in 191 systems are included. Data are presented in two tables, one for orbital and physical properties and one for companion designations, discovery information, and reference codes for data values.

Data are ordered by permanent number, then provisional designation. This data set is complete for binary/multiple components reported through 31 March 2011.
