ELI5: If a room temperature object is left in outer space for an hour, would it come back colder, warmer, or the same temperature?

With what little I know about physics, in order for something to lose/gain heat, there must be a transfer of heat from one object (or particle) to the next. So in space, which is mostly void of "stuff", would something be unable to transfer (a significant amount of) heat?

Heat is also transferred by radiation, which does not require a medium (particles, like air/water/etc). Your object in space would radiate heat and start to cool, but you also have to account for incoming radiation (from the Sun, for one example). So, your answer depends quite a lot on where you put the object. If the object is radiating more heat than it's receiving, it will get colder.
