such thing as comet shower?

Answer 1

No. But a meteor shower is the result of a comet that leaves dust particles in its orbital path, which the earth's orbital path can intersect if the two are aligned just right.

Answer 2

We've actually seen a small one in the news a few years ago. The comet train that hit Jupiter and had the astronomers practically babbling like idiots they were so excited. Was that perhaps Shoemaker-Levy 9? I forget, but you could look it up. Anyway, it was a comet that broke up into parts and resulted in some really spectacular pictures of what happens when a comet hits an atmosphere.

Comets, like meteors, are slaves of gravity. So they would hit us with the same general speed as meteors.

The odds, however, favor swarms of rocky meteors rather than swarms of icy intruders. That is because the rocks are closer (in the asteroid belt) than the most likely sources of ice shards. The nearest sources would be the rings of Saturn or the Oort cloud; in both causes, anything heading our way would most likely have been diverted by collisions with other objects.

Answer 3

In a way, the recent Geminid meteor shower WAS a comet shower. The meteors are, after all, grains of dust from a comet which passed through Earth's orbit some time ago, or at least the tail of one did. What you will never see, though, is actual comets streaking through our skies like the Geminids. One less thing to worry about, eh?

Answer 4

No, because comets are single objects that never actually enter our atmosphere - what we see as a comet is really the dust and gas from the comet ionized by the solar wind.

Meteors are the streaks of light that occur when small objects (some the size of sand grains, some as large as a loaf of bread) enter our atmosphere and burn up from friction.

Meteor showers (that's when there are a lot of meteors in a few days or weeks) are related to comets. The material that enters our atmosphere is from streams of dust and pebbles left behind by comets in their orbits around the sun. When the Earth enters one of these debris streams, we get a meteor shower.

But comets and meteors are not related phenomenon.

Answer 5

Not in the same way we see meteor showers. Simulations have shown that a large body, like a small star, passing through the Oort cloud, could cause comets to plunge into the inner solar system in large numbers. This has never been observed, though. Still, this would be observed as many comets moving slowly through the interplanetary sky over months, not seconds, like meteors in our atmosphere.
