Photometric campaign on (65803) Didymos in 2011


The binary asteroid (65803) Didymos is a target of the Binary Asteroid in-situ Explorer (BASiX) mission (PI D. Scheeres) that was proposed to NASA in September 2010. It is also a candidate for detection of the BYORP effect (McMahon and Scheeres, Icarus 209, 494, 2010; Pravec and Scheirich, BAAS 42, 1055, 2010, also available here).

Following table summarizes planned observations of Didymos in its 2011 apparition.
