If the Sun generates so much heat, why do astronauts have to worry about freezing?

Question

I see a lot of videos and shows where, if a person gets thrown out of an airlock, they immediately freeze to death. Disregarding the usual Hollywood exarcebation, WHY is space “cold” if the Sun generates so much heat radiation that it warms our very planet every day? Shouldn’t space be “warm”, then?

Answer 1

Space is a vacuum .. because space is a vacuum, there are nothing to convect heat from the sun,
