Collisions between objects in the Kuiper Belt produce fragments that become comets. The comets are known as short-period comets. Short-period comets take less than 200 years to orbit the sun. Therefore, they return to the inner solar system quite frequently, perhaps every few decades or centuries. Short-period comets also have short life spans. Every time a comet passes the sun, it may lose a later as much as 1m thick.
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.
Because they aren't traveling towards the sun. Comet tails are caused by debries being burned off.
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
Two things: 1. Comet tails do not follow along behind the comet. Comet tails always point away from the Sun. 2. Comets are not rocky, they are icy.
The tail of the comet is made up of melting ice. When the comet gets close to the sun, the melted ice becomes the gaseous tail.
It depends on how fast the comet is going.
Because the comet is going so fast there looks like the comet has a tail.

Some comets have tails reaching 160 million kilometers long.

The Sun boils off material from the comet and this is seen as a "tail".
Only by accident. A comet's tail will point away from the sun.
