Isn't it that solar is the sun, Why is it that solar wind is cold?

Answer 1

The solar wind's temperature varies a great deal but is generally very hot, of the order of 10000's of degrees C.

As human what we normally encounter as temperature is heat transfer. This is due to molecules or atoms colliding we our skin as transferring their energy. We feel this as either warmth or coolness.

In space and in the solar wind the density of the atoms or molecules is very low; so compared with the earth, where the density is high there is very little interaction between the atoms/molecules and so the transfer of energy is low. The upshot is that although the temperature is high it is not transferred/felt by us or an object such as a spacecraft.

I hope this helps.

Answer 2

You realize that "cold" is a VERY relative term, don't you. That said, solar wind is simply particles ejected from the sun through "cold" space. While these particles radiate their energy during their celestial flights (and thereby lose heat and energy), very highly energetic particles are creating the Northern lights, ripping through satelites, and even traveling right through the earth (some have that much energy) so that you can literally see the sun at midnight by pointing a very special telescope straight down at the earth aimed at the sun on the other side. Obviously, all the particles begin as hot as the outer layers of the sun, but hot objects radiate (Law of Cooling, along the lines of blackbody radiation) as you have doubtless seen with red hot machine gun barrels and white hot liquid metal in chemical refinery plants.

Answer 3

I have never heard that the solar wind is cold. The solar wind is a stream of particles emitted from the sun. They are very energetic and therefore probably hot.

Answer 4

solar winds are the winds genrally from the sun,as they come out of the sun and enter the the space between the planets which are very cold,they lose the temperature to the surrounding,due to this they lack heating effect..

Answer 5

It isn't that it is hot or cold, it is active energy and we are very sensitive to it, having evolved under an atmosphere blanket that protects us from the most active particles. Close to the sun it is hot, further away it is colder in terms of temperature in space, but those are just things we notice because they affect us. Take the "human" out of the equation.

Answer 6

ever heard the weather say it is 33 degrees and 26 with the windshield. that means that with the wind it will be cooler. same thing with solar wind. it cools off.

Answer 7

no idea may be because of vaccum arround the sun
