Halley's Comet is unique because it is one of the most famous comets known to humanity due to its regular appearance every 75-76 years. It is also the only short-period comet that is visible to the naked eye from Earth and has been recorded by humans for over 2,000 years. Additionally, Halley's Comet contains a nucleus made of ice, dust, and rocky material that gradually vaporizes as it gets closer to the Sun, creating its iconic glowing tail.

Answer:- Briela's comet appears after 6.6 years. Its correct name is biela's comet. Di vico is not comet. Halley appears after 76 years. Donati is a non period comet. It appeared once only in 1858. I think correct answer is Biela's comet. If there is any other opinion mail me.
From Earth it would be the Sun, which, however not a planet, but a star

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.
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.
Shoemaker-Levy 9 is unique because it was a comet that broke apart and collided with Jupiter in 1994, creating a series of impacts that were observed from Earth. This event was significant because it was the first time a comet collision with a planet had been observed by astronomers. The impacts left scars on Jupiter's atmosphere that persisted for several weeks.
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.
There is nothing that makes any individual unique.
