Have you ever looked up in the sky and seen a little ball creeping by? If so, did you wonder what it was? That little ball is called a comet. Comets are small, fragile, and irregularly shaped. Most are composed of frozen gas. However, some are composed of frozen gas and non-volatile grains. They usually follow very strict paths around the sun. Comets become most vilsple are saying that the comet is going to Be huge, and others say it will be small. We will never know though because we can not see the nucleus of a comet. The part of the comet we see is the tail. The tail of a comet can be over 10,000 kilometers long.

In all, comets, the history of comets, and comets waiting to be discovered is very interesting. I think that one day we will get to see the nucleus of a comet, and be able to watch comets form in the Oort Cloud.

we have just figured out that we are goind to be hit by comets in 877 years and 11 months, this is a long time away but i think we will be ready by then. the comet that is going to hit us is 0.6 miles across so if we were to go head up with it it would create 10 mile creater.
