It becomes a puddle!!!
As it goes through space, the sun (or other stars) melt it. This creates a big tail behind the comet.
All comets have tails when their proximity to the sun is such that the icy debris in the comet is warmed enough to melt and fall 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.
Comet Tempel-Tuttle.
The tail of a comet is made up of a combination of frozen rock, and ice particles coming off the comet and is lit up by the sun. If you were to be in this tail, you would face: subzero temperatures and constant pummeling by SOLID ice and rock.
It's called a comet. They're usually cimposed of rock and ice. As the object gets close to the sun, the heat causes the ice to evaporate, and the rock to melt. This is seen as the comet's 'tail'.
The comet's tail is in front of the comet, not after
The coma, the nucleus, and the tail are the parts of a comet after the tail has formed.
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.
The tail is actually moving away from the comet. The solar wind pushes the dust and ice particles away from the comet as it melts. The ice particles reflects the light from the sun allowing us to see the tail. In fact, the comet's tail is never behind it. It is always to one side of its direction of travel.
Venus is a planet, not a comet, so it does not have a tail.
