  1. Known matter in the outer area is cxalled Oort Cloud. It must be about  3 degree K there!That is minus 270 deg c


  2. Actually, believe it or not - it's here on Earth.

    In the hunt for "Dark Matter", they've chilled a pool of xenon gas down to 70/1000 of a degree above absolute zero, down in a mine in Minnesota.  

    Considering that deep space is still "heated" by the cosmic background radiation to about 4 degrees kelvin, the Dark Matter searchers have created the coldest known place in the universe... in Minnesota!

  3. The furthest away from the sun I presume. If there's no heat from the sun - you'll freeze. So just keep going out and out and out and out right to the edge of our solar system and theres your answer. Or, it might be like right behind Pluto because its so far out and like it blocks out the sun. Or maybe thats to small so its more like behind Neptune. Either way, it would be un-imaginably cold.  

  4. The Oort cloud, which is the outer limits of the solar system.  

  5. neptune's moon triton

    38kelvin

    this is the best answer ull find

  6. At the Oort cloud!

  7. the farthest reaches of the ort cloud

  8. Triton. a moon of neptune. 400 degrees below zero Fahrenheit

  9. I'm assuming you mean on a usual basis. Well, I'll betcha a dollar to doughnuts the coldest place in the solar system proper is a place where it faces away from the sun the longest, not necessarily the most distant. In fact I had a hard time accepting this when I read about it 15 years ago. Pluto has the lowest average temp of the major bodies. Triton is claimed to be one of the coldest. But its the dark side of Mercury that slips down to the depths of cyrogenic coldness. I don't have access to specific temps, but I'm sure Pluto and Mercury are rivals in the cold department.

  10. The further out you go, the colder it gets.
