  China's second lunar orbiter, retasked to an interplanetary explorer. Entered a 119 x 8599 km lunar orbit on 1 October at 03:14 GMT. By 9 October it had maneuvered to its operational 100-km circular lunar orbit. On 9 June 2011, its lunar mission complete, it was maneuvered out of lunar orbit, and arrived at the Sun-Earth L2 Lagrangian point on 25 August 2011. It then followed the interplanetary gravitational superhighway to a 1.02 AU x 1.03 AU x 0.2 deg solar orbit, leading to a flyby of the asteroid Toutatis on 13 December 2012 at 08:30 GMT. It came within 3.2 km of the planetoid and returned detailed images.
