Abstract We calculate the electrostatic potential of silicate, graphite and carbon submicronic grains in the coma of comet P/Halley located at 1 AU from the Sun using the “orbit-limited” solution. The physical properties of the materials as well as the plasma parameters of the subsolar cometosheath are taken into account. We find that the potential lies between −3 and +4 volts in all cases, under likely conditions. It could be negative, between 0 and −10 volts, if the plasma would be a little more dense than usually admitted, as suggested by recent measures.
