whats the temperature in outer space?

Question

if you have a smartass answer, please post it, but i would like to know the truth as well

Answer 1

Zero degrees Kelvin is -273.15 degrees Centrigrade. This temperature is defined as the loss of movement on the molecular level. Deep space hovers just a fraction above this temperature.

Answer 2

A corollary question is how does one measure the temperature of a near vacuum? If you stick any thermometer into deep space, Planck's radiation equation explains how the thermometer is able to thermally equilibrate with the rest of the universe, through emission of electromagnetic energy.

In general, you need to be FAR away from any star to get to the cosmic background temperature of 2.7 K. In Earth orbit, the solar radiation is about 1300 W/m^2, and a perfect blackbody will radiate sufficient energy to get to around 300 K. On the other hand, in Pluto's orbit, there's so little solar radiation that the temperature drops to around 35 K.

Answer 3

It's not actually 0 K anywhere (0 K is -273 C and minus a lot F). The background temp of space is about 2.7 K, which is the temperature of the photons left over from the big bang - the cosmic microwave background. Even if there's nothing else (a vacuum), you find these photons everywhere in the universe.

Answer 4

Astronomers tell us that the solar wind and interstellar gas clouds are over a thousand degrees and sometimes in the millions, but also that the cosmic background temperature is minus 455 degrees Fahrenheit. A thermometer in space will read somewhere between these two extremes, depending on whether it's in the sun or the shade.

Answer 5

Even in the deepest, emptiest parts of space there is a temperature of at least minus 454 degrees Fahrenheit. This temperature fills all of space because it's the left over heat from the Big Bang that created our universe.

Answer 6

Thermometers may opt to paintings in area yet may opt to be at threat of being heated by the sunlight hours's radiation only as they're the following, in elementary words extra so. In shadow, a thermometer in area may opt to degree the entire means of atoms and molecules colliding with it, which will examine in about 3 Kelvin or -270 C. commonly used thermometers does no longer paintings at that temperature everywhere they were placed because interior the adventure that they use a liquid it may opt to freeze and interior the adventure that they were liquid crystal it does no longer undergo a replace of colour as a results of lack of ability of means. in all likelihood there are different forms of thermometers which do function at such low temperatures.

Answer 7

It's hot as Britney Spears up there. I mean, the sun is chillin' up there with the moon, so I'd say it's about 200 Degrees Fahrenheit.

Answer 8

In sunlight or shadow? In sunlight it's around 250k and in shadow it's -250k but in deep space the temp can drop to almost absolute zero around -450 k (k stands for Kelvins )

Answer 9

0 degrees Fahrenheit

Answer 10

the temperature is variable depending on where you are in space. for instance it will be very high close to a supernova and very low, close to Pluto.
