The gas tail is like the smoke from a ship in a gale. It doesn’t really matter which way the comet is going as the speed of solar wind from the Sun is much faster than the comet. So the gas tail is more or less radially directed away from the Sun.” If the Earth passes through the tail of a comet – such as happened with comet Swift Tuttle in August – we experience a meteor shower.
