The second light is a useful unit of length in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in a vacuum in one second, and is precisely equal to 299792458 meters (983571056 feet). In space, the lack of air pressure causes the body to expand. Oxygen from the rest of the body will also expand, but you won't explode.
The skin is elastic enough to keep you intact. Depending on where you are in space, this process can take between 12 and 26 hours. However, if you're close to a star, you'll be burned to a crisp.
