How close would you have to get to the sun for it to feel "hot" in outer space?

I know that space is a vacuum and therefore doesn't retain heat and whatnot, but I assume that if you got close enough to the sun it would still have to be pretty hot, no?

Well, a vacuum does not retain heat as you say.  However, it's a perfect medium for transmitting heat.  So, Earth is 93 million miles away from the sun (plus or minus) and you can certainly feel the heat the sun generates.  Astronauts who go on space walks wear suits specially designed to draw away excess heat the arises when the sun appears.  In an nutshell, you don't have to be very close to the sun to feel it's effects.
