As the comet moves farther away from the sun, the tail begins to diminish, as the heat and solar wind pressure on the cometary nucleus decreases. Far away from the sun, near the most distant point in it's orbit, the ices in the nucleus are frozen, and the comet is quiet.
A comet's tail lengthens as it approaches the sun due to greater solar winds. A comets tail always faces away from the sun.
Comets can travel varying distances depending on their orbits. Some comets have orbits that take them far out into the outer solar system, while others have short-period orbits that keep them closer to the sun. Some comets can travel billions of miles during their journey through the solar system.
The sparse sphere of comets that surrounds the sun and planets is known as the Oort Cloud. It is a vast region of space that is thought to contain billions of icy objects and comets. The Oort Cloud is located far beyond the orbit of Pluto, extending up to about 1.6 light years from the sun.
No. Comets are not moons as they orbit the sun, not planets.
Comets go around the Sun in a highly elliptical orbit.

Always changing, and no two comets are the same. Some comets, like Halley's Comet, don't come too close to the Sun each pass, and don't get all THAT far away; between 0.5 and about 30 AU, for Halley. Other comets go a REALLY long way out; hundreds, perhaps even thousands of AU out from the Sun. And of course, there have been at least six comets observed, so far this year, to actually fall INTO the Sun and be destroyed.
comets orbit the sun
Comets are balls of ice and dust in orbit around the Sun. The orbits of comets are different from those of planets - they are elliptical. A comet's orbit takes it very close to the Sun and then far away again.
No. Comets orbit the sun.
No. Mercury has nothing to do with comets. Comets are objects that orbit the sun independent of the planets.

no only comets.
that comets circle the sun

actually several comets circle the sun a year!
