What Is The Coldest Place In the soalr system?

Answer 1

First, there is no place in the universe that is naturally "absolute zero." In fact, up to this point, mankind has been unable to invoke absolute zero in anything. Check this out:

"If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very very long time. Once it cooled off, it would read 2.7 Kelvin. This is because of the "3 degree microwave background radiation." No matter where you go, you cannot escape it -- it is always there." [See source.]

Second, I suspect we've not measured the "coldest place" in our solar system. There are a lot planetoids and planets we've not yet measured. But here's what would make it the coldest place.

It would be very far from our Sun, but still captured by its gravity so it stays in some semblance of an orbit. Some solar comets, like Halley's Comet, go way outside the Kuiper Belt that is beyond Neptune in our solar system. "The Kuiper belt (pronounced /ˈkaɪpɚ/, to rhyme with 'viper') is an area of the solar system extending from the orbit of Neptune (at 30 AU) to 50 AU from the Sun." [See source.]

When Halley retreats from the inner solar system, it goes out beyond the Kuiper Belt. When it is at apogee (farthest away from the Sun), the comet is probably about as cold as it gets...close to 3 deg K. Not only is it about as far away from the Sun as one can be and still be in its gravitational influence, but as a block of cinders and ice, it has no internal source of heat, like some planets do.

There is a yet theoretical belt of comets captured by our Sun. It is call the Oort Belt. [See source.] Lying well beyond the Kuiper Belt, one might speculate the Oort Belt contains the "coldest place" in the solar system. [See source.]

Answer 2

Even though there is info to speculate,mankind still has a far way to go,in knowing about our solar system,much more our universe,it is simple we know to too little about our solar system to classify were is the coldest part.
Perfect example of how much man kind has been browsing,is our oceans,we still have a long way to go in exploring them,and there are still alot of creatures and features left unknown to us,even on land,especially in the Amazon rain forest,so how are we going to classify apart of the universe or solar system to be the coldest spot.i know the question was about the solar system,and not about our plane and its creatures, but just to illustrate the point,we need more info.
But still it shows that we are making and effort to know our surroundings,as we are like microscopic creatures to our Universe.
However base on past expedition,Triton a moon of Neptune appears to be the coldest because of it being cove-rd by methane gas in its liquid form,and that's really cold.

Answer 3

The further away you are from the Sun, the colder it gets briefly put. And yes, that is why Pluto is the coldest Planet in the Solar System.

Answer 4

Triton, the largest moon of Neptune, appears to be the coldest place in the solar system, Voyager 2 scientists reported.

Answer 5

Scientists analyzing recent samples of comet dust have discovered minerals that formed near the sun or other stars. That means materials from the innermost part of the solar system could have traveled to the outer reaches, where comets formed. these minerals were found hight -temperature of materials in the coldest place in solar system .

Answer 6

scrappin momma is right when it comes to which place is the coldest in this solar system, But there might be colder places in the universe...

Answer 7

There is a dwarf planet beyond Pluto called Eris, its about 30K

Answer 8

The planet Pluto
it doesn't get heat from the sun to warm it.

Answer 9

The white house....

Answer 10

Back side of Pluto would be a bit cool this time of year....
