The tail of a comet is longest when the comet is closest to the sun, as the sun's heat causes the comet's icy surface to vaporize, creating a bright glowing tail that streams away from the comet.

A comet's tail is always pointed away from the Sun due to the solar wind. As the comet moves closer to the Sun, solar radiation and solar wind push the dust and gas away from the comet, creating the tail that appears to extend ahead of the comet in its orbit.

Comets are the celestial bodies that appear in the sky at regular but long intervals and have a tail. This tail forms as a comet gets closer to the sun, causing ice and dust to vaporize and stream away from the comet, creating a bright extended tail.
