Scientific paper

What is known about the mass production, gas velocity, asymmetry factor, and angle of the nucleus of Comet Halley is examined in order to arrive at an estimate of the average density of the nucleus. An estimate of 0.6 g/cu cm + 0.9 or - 0,.4 g/cu cm is obtained. This result is compatible with 'snowball' models of the nucleus, although a more compact ice structure could correspond to such a density value.
