eli5: Why isn’t outer space hot (or at least not freezing)?

2.65K views

The sun warms up our planet but space is cold. If I lit a candle and stood 20 feet away, I could see the light but not feel the warmth. So, why do we feel warmth from the sun but space isn’t warmed by it?

Because space is nothing. What is warm on earth is the air. Or any object / particle. There is no air in space. Nothing to be hot out there
