Scientific paper

The mass of the nucleus of comet Halley is evaluated from the lag between successive perihelion passages and "jet propulsion" effect created by the mass outflow from the nucleus. A mass of ≡3×1011t was found for the nominal model of the outflow. This value combined with the volume defined by the Vega-1 and Vega-2 TV data lead to the average density of the nucleus 0.6 g cm-3.
