Yes. Like all multipliers the heat of the sun requires not only it’s self but that which is to be acted upon. If you are a handsome wet rock, the distance you are to the sun effects how your heat is multiplied.

Vacuum doesn’t have a temperature~

Is water wet?

No, water makes other things wet.

But you will if you sit in a vacuum for a while without a radiation source nearby, and it will be quite low.

Are you dissipating heat in a vacuum, though? Pressure shenanigans aside, would someone’s body heat slowly, continually build up, or would they freeze?

If you could somehow prevent yourself from dying due to lack of pressure, you would radiate about 650W more than you generate.
That’s using the Stefan Boltzmann law, at normal body temp, perfect blackbody and 1.5m2 of skin. And then assuming 2000kcal a day.
You’d cool down pretty quickly.

Good to know! I didn’t realize humans would radiate heat so much, I wrongly assumed it was more convective and relied on atmosphere

So how long do I have? Also, if you guys could hurry with the answer…?

Heat buildup is actually a problem in space, yeah. You need heat sinks on long term space flights.

You constantly radiate heat. The warmer you are, the faster you radiate it away. In space this does not stop.

Have you ever looked up at a clear summer night sky? Your face will feel cold. Colder than when looking at the ground. That’s because there’s not as much stuff radiating heat at you up there.

It would be pretty warm at earth if the planet didn’t radiate some of the heat away
