Comets originate in the 'Oort Cloud' - a cloud of ice and debris surrounding the solar system far out beyond the orbits of the planets. If one of these pieces of debris manages to succumb to the sun's gravitaional pull rather than hat of the surrounding bits of debris, it will begin an orbital path round the sun, in an elongated elipse (like a cigar-shape). This is what we call a comet. As the comet is in orbit round the sun, it will reappear near earth at intervals.Some comets have a relatively short reappearance time - the most famous being Halley's Comet at 76 years. Some comets take 3000 years to reappear or even more. When it approaches the sun at distance it is simply a block of ice and rock. However, when it gets near the sun, the solar wind ( a stream of radiation from the sun) and radiation melt the surface of the comet so that a tail emerges. (actually two tails form - but the reasons need not be explored here). The characteristic tail is what we see when looking at a comet. The tail always faces away from the sun (not behind the comet in the direction of travel, which is commonly, but wrongly believed) because of the solar wind pushing away debris in a direction opposite to the sun. After its orbit the comet will return to the Oort cloud as its tail disappears (as the solar wind has less effect) to begin its journey round the sun again. After several journeys, the comet will lose more and more material (that forms the tail) because of the Solar wind. There will come a time when the comet eventually dies out like an icecube melting on a hotplate.
The comet's tail is in front of the comet, not after
The Comet ended in 1933.
Blue Comet ended in 1941.
Air Comet ended in 2009.
Air Comet Chile ended in 2008.
The three main parts of a comet are the nucleus, coma, and tail. The nucleus is the head of the comet, the coma is the middle, and the tail is the end of the comet.

As of May 20, 2014 the next comet that will be coming by the Earth is Comet Faye at the end of May 2014. In June 2014, Comet Brooks 2 will be passing the Earth.
A comet has a gravitational pull that attracts dust and ice from space which crates a tail behind it
Comet and cupid
Probably NOT because it said " THE END" at the end of Sozin's Comet.
Begin: Hitler End: Murica
Head: The front of the cometNucleus: Middle of cometComa: The coma is a halo of evaporated gas (water vapor, ammonia, carbon dioxide) and dust that surrounds the nucleus. The coma is made as the comet warms upTail: The end of the comet
it ends by the sun vaporizing it because of the suns heat. all that is left of the comet after it's vaporized is water, methane, and ammonia
As it goes through space, the sun (or other stars) melt it. This creates a big tail behind the comet.
You begin with one and end with four.
Begin: Stock Market Crash End: WW2
The Analogy to begin is to end as actor is to actress.

no I am the biggest fan of Avatar so at the end of sozin's comet the episode katara and aang makeout and the show ended there.

The day when a pay period will end and begin will depend on the employer. Most pay periods end on Thursday and begin on Friday.
it could be the end of the earth
Probably because they were uninformed. Science has come a long way since then and we know Haleys Comet will probably never collide with Earth and end all life.
