What is the ambient temperature in space?

Question

What is the ambient temperature in space?

Answer 1

There isn't in a vacuum.

Answer 2

In vacuum? there is no ambient temperature, as there is nothing to have an ambient. A small object placed in space will have a high temperature if the sun is shining on it, otherwise a very low temperature.

In a space station? whatever the temperature controllers are set to. They will have to supply heat when the station is in shade and cooling when it is in the sun.

Answer 3

it varies depending on how far away from the sun it is. but in most parts i would say 0 K

Answer 4

About 3 degree K.

Based on the microwave background radiation CMB.

This is the radiation left over from the big bang.

Note: there does not need to be molecules

to be a temperature. Temperature is energy.
