Comets are unique due to their composition of ice, dust, and rock which vaporizes as they approach the sun, creating a glowing coma and tail. They come from the outer solar system and follow highly elliptical orbits, making them occasional visitors to the inner solar system. This distinguishes them from asteroids which are made of metal and rock and mainly orbit in the asteroid belt.

Solar wind makes a comet's tail always point away from the Sun.
I assume you are asking about Shoemaker-Levy 9. This comet smashed into Jupiter and disturbed the appearance of Jupiter for a time. Perhaps what makes this unique is that the astronomers for whom this comet was named predicted its demise and observed the detritus kicked up. That was a first. As for the event itself - the plunging of a comet into the gas giant Jupiter - that could hardly be called unique. As the largest planet in our solar system, Jupiter absorbs a lot of blows and protects the inner planets. Without Jupiter, Earth would be much more pockmarked by meteors, comets and other orbiting objects whose paths tangle with the orbit of the Earth. For an excellent - and much fuller explanation - look up "Comet Shoemaker-Levy 9" in wiki answers.
There is nothing that makes any individual unique.
Halley's comet appears because it is a comet that orbits the Sun. It as a highly elliptical (oval) orbit which makes it seem to fly out of the solar system and back.
The sun makes a comet appear bright. A comet is usually made up of ice and rock. The ice reflects the light of the sun very well.
