Without an atmosphere in space, how close would you actually have to get to the sun before it would be hot enough to kill you (from the heat, not just radiation)
In: Physics
This isn’t really a very straight forward question. For the most part, as long as there isn’t junk in between you and our sun, your blood could still boil right outside Earth’s atmosphere. If there’s anything between you and the sun that can block direct sunlight from hitting you, you’ll start to freeze to death fairly quickly.
I seem to recall an estimate saying a human with a perfect spacesuit could survive comfortably around twice the distance from the Earth, so around 300 billion meters (186,000,000 miles), given the rough volume of a human and a rough estimate of surface area absorbing heat. But that all depends on the space around you.
