I heard that the temperature of Pluto is around -380 F. This would instantly kill any human. Pluto is relatively close to a star (it orbits our sun) and gets its heat from that star. Therefore, how cold is it in deep space where no stars are nearby?

What is "Kelvin" and "Absolute Zero"?
In layman's term's, how cold is that?

It's close to absolute zero. All molecules have some degree of movement, and that movement slows down the lower the temperature is. At absolute zero, that movement theoretically stops. The temperature has been calculated to be roughly -273C.
Kelvin is simply the Celcius scale -273, in other words, water freezes at 273 Kelvin and boils at 373 Kelvin. Absolute zero is 0 Kelvin.

The coldest anything can ever get is -273 degrees celsius (absolute zero: about -459.4 F) but in any given region of deep space the cosmic microwave background radiation must be taken into account which has a fairly constant temperature of 2.725 kelvin (-270.275 C or -454.5 F) which would be the temp. in deep space away from any stars etc. : )
Kelvin is the same scale as celsius except that -273 C is 0 K for convience purposes in physics.

Deep space is around 3 degrees Kelvin

The coldest attainable temperature is absolute 0. besides the shown fact that, this will not be attainable to realize for the reason that our universe itself has a temperature, left over from the massive bang. As you comprehend, something chilly in a heat room heats up and turns into an identical temp because of the fact the room. it incredibly is actual of any area interior the universe too. The cosmic background radiation has been shifted all the way down to easily approximately absolute 0, yet is fairly above it. there is a precise discern, yet i don't keep in mind it precisely. it is latest in many texts on cosmology.

To expand Eugene's answser, 3 Kelvin is about -270 C.
That is about -454 degrees F.
