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.
as far as i am aware it is haley's comet
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.
Venus is a planet, not a comet, so it does not have a tail.
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.

The coma, the nucleus, and the tail are the parts of a comet after the tail has formed.
The comet's tail is in front of the comet, not after
Venus is a planet, not a comet, so it does not have a tail.

The tail of a comet is luminous because it scatters and reflects the light from the sun.

The tail of a comet is over a million miles long.
