the answer is idk
Yes, it does have brighter and longer tail, because during its closest approach to the sun, it was most effected by the sun (evaporating the more water from the comet).
When it was further out, when the sun is much further, it will gradually become cooler, no ice evaporating too space, and no tail.
It may or may not develop a tail if the comet is small, or if its perihelion is outside or beyond the orbit of Mars.
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.
A comet is comprised mostly of ice. The tail of the comet is caused by cosmic winds, from our sun, blasting particles off the comet's surface, the tail does NOT point in the opposite direction of travel, as one might expect, but points directly away from the source of the solar winds. That's why a comets tail, (from our perspective) may be traveling in a certain direction but have it's tail pointing in the SAME direction.
Venus is a planet, not a comet, so it does not have a tail.
A comet is a space thing that has a heavenly body and a tail. The most famous comet known is Hailey'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.
Close to or at perihelion.
The pressure of the sun's light shining on the wispy gasses vaporizing from the comet's head push the tail of the comet away from the sun. While it looks like the "tail" of the comet is trailing behind, the tail always points away from the Sun. So after the comet's perihelion (the closest approach to the Sun) the "tail" is actually LEADING the comet!

Yes.
no
The next predicted perihelion of Halley's Comet is 28 July 2061
The perihelion of Halley's comet.
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.
In the Tail of a Comet was created on 2000-04-25.
