Travel destinations 2015 for Antitail Occasionally, comets may have a thin mini-tail that points toward the Sun the socalled antitail. This happens, from the Earth-dweller’s vantage point, when a comet’s orbit takes it close to the plane of Earth’s orbit. The antitail consists of larger particles of dust recently expelled from the comet that are not so easily pushed back behind the comet and remain in the same orbital plane as the coma. When Earth moves near to the plane of the comet’s orbit, observers can see not just the main part of the tail on the side of the comet away from the Sun, but also some of this larger material still remaining close to its orbital plane, which appears to poke out in front of the coma on the sunward side. An antitail may also be seen when Earth’s position relative to a productive comet is such that the rear part of the comet’s tail is seen, in projection, on the sunward side of the coma. Antitails may take the form of a fan or a spike, depending on the position of the comet relative to the ecliptic plane. Comet Arend-Roland on April had a fan antitail and on April a spike fig.
