The comet's "tail" is a stream of dust and vapors that melt and get pushed out

of the comet by radiation pressure from the sun. The tail appears only when the

comet is relatively near the sun, it's longest when the comet is nearest the sun,

and it always points away from the sun, no matter which way the comet is moving.
