Description
Imaging experiment results have been used to generate a three-dimensional model of the nucleus of Comet Halley in which overall dimensions are 7.2, 7.22, and 15.3 km, defining a volume of 365 cu km. Ratios of the inertial momenta are 3.5:3.4:1; the longest inertial axis is slightly inclined to the body's geometrical axis, and overall shape is very irregular. Four brightness features are identified, and two of these are suggested to be related to slope variations displayed by the Giotto images of the comet: one of these features is the ducktail. The model also reproduced the outlines of VEGA-1 images. 15 refs
