i suppose that this only in deep space hundreds of miles from any planetary, or solar sources, but i just wanted to know how far away one would have to go to get to absolute zero...naturally anyway...

i must ask you to look at the incompetence of several people below... if you don't know what the whole question is about you should never surf science and mathetmatics, besides try to answer a question about it, type it into google , wikipedia, or dictionary.com ...

Absolute zero is 0 deg Kelvin. This is where there is no molecular movement. I suppose theoretically it is possible to reach that temp in nature in some pockets of matter (henceforth referred to as the pocket...a collection of matter that is at absolute zero). However since whatever place that is, no matter how big it is, no matter where it is, neighbors some form of matter that is NOT at absolute zero, there would be a constant fluxuation on the fringes of this pocket of matter being warmed up by or cooling the neighboring space to change whether it is actually AT absolute zero...and this would actually change the size and shape of the pocket and determine its influence on the neighboring matter. You have to look at size and shape because this determines the surface area, aka fringes, of the area that is touching something that is moving and how far away you are from the center of the pocket. Deep in the heart of the pocket, the molecules may remain still for a while, insulated by other matter at absolute zero.
Presumably the principles of temperature work the same no matter where you are on the scale, from very very cold, to very very hot. So let's warm things up to a place that is easier to understand. Quite frankly, I never deal with anything at 0 deg K but I deal a lot with ICE!
Right now, I am drinking an iced beverage. When I took the ice out of the freezer, it began to melt, because my house is warmer than the ice, and the surrounding warmer space is larger than the ice cubes, even if they keep each other cold. I can add a drink which will be cooled down by the ice but also warms the ice cubes and over time, the ice will melt and the drink will become room temperature. Such is the influence on two things at different temperature.
But it depends on how big each thing is. If I had a block of ice as large as a TV set and added a teaspoon of drink to it, chances are it would freeze to the ice. If I added a tiny chip of ice to a pot of boiling water, it would melt immediately.
And then surface area matters too. If I froze a piece of ice in a tube shape, such as in a drinking straw, it would have a larger surface area than the same amount of ice frozen in a ball or cube shape. Similar, crushed ice has a larger surface area than the same amount of cubed ice. So cubes will stay frozen longer, ie, affected less by the surrounding matter...and deep in the heart of the ice cube, it is still frozen even though the ice around it is melting...until it finally has no insulation and melts too. All this to say, ice doesn't melt from the inside out, it shrinks.
Does this make sense?

Absolute Zero is the limit and nothing gets this cold. Deep space has been shown to get down to a few degrees K. Evidence for this comes from the spaces between rare black diamonds called carbonado that were formed in space. The isotope concentrations of gasses trapped show that they could only have formed at such low temperatures.

Absolute zero, 0 Kelvin, is an ideal and would not be met no matter how far away you were from a source of heat. It has been approached artificially, but the inefficiencies of machines prevent completion to absolute zero.

No. The third law of thermodynamics is that you can't reach absolute zero. The outer universe is at about 3 degrees Absolute, leftover heat from the big bang. Nothing natural is colder than that.
On Earth, scientists can make really neat refrigerators that can get down to a tiny fraction of a degree. But not to zero.

No, it's not happened on earth, either naturally or artificially yet (although they can get very close).
Note that space isn't at absolute zero, either. There are a few bouncy molecules out there floating around, and any kinetic molecular energy at all equates to some non-zero temperature.

No. Even in the lab, absolute zero is not attainable by the laws of thermodynamics and in the universe, no matter where you go, you're bathed in the roughly 3 degree Kelvin cosmic background radiation.

I don't believe so... absolute zero would involve zero molecular/atomic movement... space, or even deep space would be pretty much the only location naturally, if even there.

I think there is not an absolute Zero any where

Absolute zero WHAT. Intelligence? Yes, right here at this question.

Naturally "NO!" according to your Parameters!
