Space (empty space -- vacuum) has no "hot" or "cold" because those are defined by molecular motion, and there aren't any molecules to move. an object painted black in orbit around the Sun at the distance of the Earth might get to a (nearly) warm temperature. If there was no solar radiation in space, the thermal energy of any object there would be radiated away as infra-red radiation. - Use the force-field, if you would like to life a little longer.
