Where Do Comets Come From?


The comets we see from Earth come from the Kuiper Belt and the Oort Cloud. The Kuiper Belt is a massive belt of comets and rocky debris in space that begins just outside the orbit of Neptune and extends to approximately fifty-five Astronomical Units from the Sun. Many objects in the Kuiper belt consist of a mixture of frozen water/ammonia/methane and rock. The Oort cloud could have as many as a trillion comets and encompasses most of the solar system. Both regions are remnants of the nebula from which the solar system was formed. It is interesting to note that the tails of a comet are only visible when it passes nearby the Sun. As these "dirty snowballs" heat up and sublimate, producing a tail of gas they points away from the Sun and tail of dust that curves along with the orbital path of the comet. Based on current scientific evidence, it is observed that comets can come from any direction in space and usually have very high orbital eccentricity.

    ReplyDelete
  23. Interesting. I wonder how long comets can go on for before burning out. Great picture too! Following for more

  35. i remember seeing hale bopp when i was a kid. all sorts of epic.

  36. Learned this in astronomy last year. It's insane how big places like the Oort cloud are. Even if the earth was to pass through it, the chances of hitting an asteroid would be so little. Yet there's millions of asteroids in it

    ReplyDelete
  37. wow, I love ASTRONOMY, thanks dude!

  43. Interesting. I always knew an Oort cloud existed but I never knew what it was, exactly.

    Btw, the gopher in the previous posts is CUTE. I've never seen one outside of Winnie the Pooh. ;)

    ReplyDelete
  61. I want to live to see Halley's comet again... Awesome blog by the way, the design looks amazing.

  62. Extremely interested in Space and the Kuiper Belt is a very interesting but less discussed part of our Solar System. Voyager 1 is currently floating through the Kuiper Belt as we speak. The furthest man man object from Earth.

  63. We should send a probe to land on a comet and search it for life. It will be hard because its moving very fast, however I think we can do it!
