* The sun is a star: It produces its own light and heat through nuclear fusion. The core of the sun is about 27 million degrees Fahrenheit (15 million degrees Celsius).
* Space is a vacuum: Space has almost no matter, so there is nothing for heat to transfer to. This means that even though the sun is incredibly hot, it doesn't directly heat up the surrounding space.
So, why does it feel cold in space?
* No atmosphere: Earth's atmosphere acts like a blanket, trapping heat and keeping us warm. In space, there's no atmosphere to hold heat, so the temperature can plummet to extremely cold levels.
* Radiation: Space is filled with radiation, which can be harmful to humans.
* No pressure: The lack of pressure in space can also cause bodily fluids to boil.
In short, the sun is incredibly hot, but the vastness of space and the lack of atmosphere make it feel extremely cold.
