Kuiper Belt Facts


The location of the Kuiper Belt at the edge of our solar system
The location of the Kuiper Belt at the edge of our solar system.
The Kuiper belt otherwise known as the Edgeworth–Kuiper belt is a region of our solar system that extends beyond the orbit of Neptune and is 30 to 50 AU (astronomical units) from the Sun.
A single AU is the equivalent to the distance from our Earth to the Sun so the approximate distance to the Kuiper belt is 4.5 billion km to 7.4 billion km from the Sun.
Due to the distance away from us there is still a lot to be discovered about the Kuiper belt but we believe there to be hundreds of thousands of icy bodies that are larger than 100 km in diameter and more than a trillion comets.
Pluto, Eris and Ceres which are 3 of the 4 newly categorised dwarf planets are found in the Kuiper belt. The Kuiper belt was named after the astronomer that predicted the existence of the system, Gerard Kuiper.


The Kuiper belt is a region of space that is shaped more like an ellipse than a circle and it is the most recently discovered part of our solar system.
We have only discovered a fraction of the objects in the Kuiper belt due to the distance the system is from the Earth. It is estimated that there are well in excess of a trillion objects in the Kuiper belt.
We have currently documented the existence of over 1,000 Kuiper belt objects (KBO). This figure is regularly increasing as viewing and measurement techniques are improving.
Pluto (one thought to be the ninth planet in our solar system but since relegated to dwarf planet status) is the most famous object that is found in the Kuiper belt.

No spacecraft has studied the Kuiper belt up close but the NASA New Horizons will venture into the Kuiper belt in approximately 2015 once it has conducted a study of Pluto.
The contents of the Kuiper belt are thought to be the materials left over when the solar system was created 4.6 billion years ago.
The Kuiper belt is 20 times wider than the main asteroid belt.
Two of the moons in our solar system Neptune’s Triton and Saturn’s Phoebe are thought to have come originally from the Kuiper belt.
Objects that can be found in the Kuiper belt (KBOs) can also be referred to as trans-Neptunian objects (TNOs).

Enough of the factual information.... I had spent some time researching informative videos on the web pertaining 
to the Kuiper belt. After alot of watching.... and being alot of bored.... I came across this video. I found it to be not only entertaining but actually pretty informative. Enjoy!


Just to delve in a bit farther, I bring up the question of weather or not life may exist within the Kuiper Belt. The Kuiper Belt isn't just a uniform collection of icy, frozen rocks. Instead, astronomers can detect lots of different colors in the belt's bodies, including reds, whites, and blues. Thanks to a new computer model, scientists now have a pretty good idea what's creating all the reds: there are organic molecules in the Kuiper Belt, buried just beneath the surface of the various objects.
NASA physicist John Cooper is quick to point out this doesn't mean there's life in the Kuiper Belt, but the reality is almost as exciting: "We're not saying that life is produced in the Kuiper Belt. But the basic chemistry may start there, as could also happen in similar Kuiper Belt environments elsewhere in the universe, and that is a natural path which could lead toward the chemical evolution of life." AMAZING! This leaves me full of curiosity!

To touch on the idea above.... I came across this video which I thought was interesting. A supercomputer simulation shows how alien astronomers might have seen the formation of our solar system from other planets.
 I found this video appealing because its not the norm. It's gives us people on Earth the ability to see what an Alien astronomer would have seen; which is not something we see every day. Don't get me wrong, I doubt that there is life on other planets; however just being able to imagine the possibility is mind boggling! I suppose only time will tell, and unfortunately I don't think that in my lifetime I will ever see enough evidence to support the idea of life on other planets.

  1. Holly,
    Nice post, I enjoyed the video's. In your opening statement you mentioned Edgeworth–Kuiper belt, who is Edgeworth?
    Thanks
    Mark

    1. Hi Mark,
      The name Edgeworth comes from the astronomer Kenneth Edgeworth who was well known for his studies involving the Kuiper belt.

  3. Great post, loved the use of video!

    "Thanks to a new computer model, scientists now have a pretty good idea what's creating all the reds: there are organic molecules in the Kuiper Belt, buried just beneath the surface of the various objects."

    Do you know what the name of the model they used was?
