How long do you think it would it take to freeze?
Body heat loss via radiation is ~140 W and the Sun's power output (at atmosphere) is ~1400 W m-2, not sure about infrared in particular, though. Must take a fair while...
I don't know exactly, Raptor, but I will say that getting tossed out into vacuum, while rendering you unconscious in a matter of seconds, and killing you in a matter of minutes, will freeze you dependent on what kind of energy or not, you happen to be absorbing. If you're shielded from sunlight, your tissues will start losing their heat to the vacuum rather rapidly, but a "hard freeze" would take more time than it would to die.
If you're in the direct sunlight, a lot longer, especially if you happen to be spinning or rotating, so solar energy is being distributed all along the body. Some heating would actually take place, dependent upon how far away you're lifeless form happens to be from the Sun (and, depending on how you may be dressed). The farther away, the less warming effect. If you're out in Jupiter space, for instance...you'll find your poor body frozen solid for sure (you won't be absorbing much in the line of thermal radiation out there). If you were in cis lunar space, it would take alot longer. If you were in orbit around Earth, or the Moon, you'd have alternating periods of solar heating and rapid cooling. All told, there are too many variables and too many scenarios to determine how fast you'd freeze!
