Most comets have their tail directed away from the Sun under the influence of light pressure and the pressure of the solar wind.
Some comets have anomalous tails pointing towards the Sun. In some comets, this direction is apparent due to the peculiarities of the projection of the tail onto the celestial sphere. In others, anomalous tail direction results from physical processes in the nucleus.
