ELI5:how hot is it in space?

i was just thinking about how weather, atmosphere, area of the world etc you are in determines how hot it is, so how hot is it if you had nothing but the rays of the sun on you in space? for examples sake.. whilst orbiting earth?

Deep space is at roughly -269 degrees centigrade, four above absolute zero, but without any air or other gases around you it's very hard to lose heat. We naturally radiate some heat in the form of photons (light), but this effect is not very noticable for cooler objects - that's why only really hot objects glow visibly. This means that in space any heat added is very hard to get rid of again, so if you were near a star the side of you facing it would heat up very quickly, while the side facing away slowly froze. If you can avoid generating too much heat of your own, and keep turning to distribute the heat from the sun you would liely find that it would still be hotter than Earth - astronauts need special cooling systems in their suits.
