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

2.36K 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?

It is a common misconception that space is cold. Although temperature doesn’t work quite the same in a vacuum, the sun still heats anything the light touches. Outside of the spacestation on the sunny side, the temperatures can reach 250c. On the shady side, it can reach -250c.
