 This bifurcated asteroid is shown to be mainly consisting of a head (small lobe) and a body (large lobe).The two major parts are not round in shape, and their surfaces have a number of large facets.In comparison with radar models, the proximate observations from Chang'e 2's flyby have revealed several remarkable discoveries concerning Toutatis, among which the presence of the giant basin at the big end appears to be one of the most compelling geological features, and the sharply perpendicular silhouette in the neck region that connects the head and body is also quite novel.
