    The tail of the comet always points away from the sun. This is because the sun is actually blowing material off from the comet. So, when the comet is moving towards the sun then the tail is behind the comet. But when the comet is moving away from the sun, then the tail is in front of the comet. That is kinda weird to think about, but that is the way it is.

    The really strange question, and one that bothered astrologists for a long time was how come there are still short period comets. A short period comet comes around the earth so often that the amount of material that is blown off from it would not let the comet last more than 10,000 years. If the solar system is billions of years old, then these comets should have been destroyed a long time ago. Because there was no good answer for this and because there was a huge need for an answer to this question they made up an answer to satisfy their need. Jan Ort ( I think Jan was the first name) proposed that there must be a huge "cloud" of debris out in space somewhere. Then for some reason a chunk got bumped and was sent toward earth. This must happen on a continual basis in order to explain the existence of these short period comets. The problem though is that we have never seen this cloud, called "The Ort Cloud". Also we cannot really explain how these chunks of debris could be bumped toward earth and travel in the way that we see them traveling.

    Short periods comets are actually evidence for the flood of Noah as described in the bible. Whoaaaoaa you say, how could short period comets be explained by the Flood of Noah and provide evidence for this story in the bible. If you are interested in learning how these comets where formed and how all of the geology on the earth was actually formed I would suggest reading the book "In the Beginning" by Walt Brown. You can buy his new edition that just came out #8 or you can read it online at Walt is a great scientist. You can read his credentials in his book. You will, also by reading his book, see that hard science, mathematics, and good interpretations of the different evidence is used. There are no miracles used to explain anything. Noah's flood actually explains everything from short period comets, to comets with little rotating moons around them, to sedimentary rock layers, to fossils, to salt and other plumes,

    to frozen mammoths, to oceanic trenches, to the grand canyon, to the Hawaiian Islands, and every other geologic feature on this planet, and some out of this planet. Remember, the bible does not just say that it rained to cause the flood. It says that all the fountains of the great deep broke forth as well. This was a huge cataclysmic event in our history. It gives us much insite to what truth is regarding earth and our lives. I would recommend reading this book if you want a thourough education in a different point of view other than the absolute religous view of Naturalism that you are currently recieving. That is an indoctrination, not an education. Getting more than one side of any issue is necessary for a good education. Then you are better informed to make a decision on what the truth is.

    A comet's tail is its most distinctive feature. As it approaches the Sun it develops an enormous tail of luminous material that extends for millions of kilometers AWAY from the Sun.

    A comets tail is composed of vapors 'boiled off' the main body

    by solar heat.

    It is driven away from the main body by the pressure of sunlight,

    and the solar wind.

    It always 'points' away from the sun, no matter which way the

    comet may be moving.

    A comet's tail is comprised of 'stuff' melting off of it when its orbit takes it near the sun. Because of this, the tail always faces away from the sun.

    "Stuff" doesn't melt off of a comet, water ice sublimes (turning from a solid to a gas right away) and is pushed back by our suns solar wind (streams of particles moving away from the sun) so that it is always trailing away from the direction of the sun no matter which way the comet is headed, even if it is moving away from the sun.

    it's very similar to why your hair blows backwards when you are facing a fan. the solar winds are "blowing" the comets tail, in the direction away from the sun.
