At this low density, temperature is very different from what you are used to experiencing. You have to work through a heat flux balance to really get a grasp of it.
Temperature is just the heat of particles moving. In the extreme case of a handful of N2 molecules moving at 1% the speed of light, it has a temperature of something like 9 billion Kelvin. But it's not going to heat you up if it hits you.

But this one is a minor volume and you would still be radiating it away much faster and not reach anywhere near the ambient temperature. In the middle of a large volume thoigh, you'd get too much incoming thermal radiation from particles within the volume and not be able to shed heat anywhere through radiation.
