Does the temperature in space remain relatively constant?

Question

Temperatures on Earth fluctuate wildly because of the atmosphere. How about the tempeture in space around Earth and does it change much? (e.g. within a day and within a year?)

Answer 1

If you read this website, http://www.madsci.org/posts/archives/dec97/880000587.As.r.html

It will explain it pretty well. A basic answer would be that any certain spot will remain constant (unless it's constantly being bombarded by radiation), but temperatures do vary across space.

In most vacuums it will be at the background radiation which will be 3 degrees Kelvin.

Answer 2

Yes.
Since there is essentially nothing in space for the Sun's rays to collide with and heat up, space itself seems to average about Zero to Two or Three Degrees Kelvin. Space near large objects may have dust particles or gas molecules scattered about within it, and those may be heated up by the Sun's radiation, causing a higher temperature than 3 Degrees K. My guess is that situation might produce 10 - 15 Degrees Kelvin, but I have no way of knowing that with any degree of certainty. I have never been higher than up in a commercial jet liner.

Answer 3

It would depend on what you mean by "around" earth. As Earth moves around the sun it casts a pretty big shadow and the part of space that falls in that shadow would certainly be cooler than the part of space that is not in that shadow. So the temperature of all the space around earth could be quite different depending on if it was in the shadow or not. The parts of space not in the shadow do have a consistent temperature.

Answer 4

Hi. The temperature is near absolute zero, on average. Even close to a star like the Sun there is nothing to absorb or reflect heat.

Answer 5

nicely first of all of the sunlight has been slowly warming up over its existence time. it particularly is predicted that existence in the international has a pair of billion or so years left in the international. So if we do final that long we can want to pass the Earth earlier issues get too warm. i think of it could be easiest to leave the Earth, yet on the comparable time it could be no longer ordinary to leave it to die. i think of that if there became a thank you to maintain it variety being engulfed we ought to consistently. i assume we could use photograph voltaic sails yet they might must be vast and that i recommend vast to pass the Earth. yet i'm specific in some million years we could ought to tech. to pass a planet. And who's familiar with we could on no account ought to leave the photograph voltaic gadget, it must be a threat Jupiter might assemble adequate mass from the nova expelled from the sunlight to variety right into a purple dwarf.

Answer 6

Yes, it remains constant, close to absolut zero.
