Some relevant temperatures

Here is a short list of temperatures that are applicable to our Earth, Solar System and Universe (in Celsius)

6000: Surface of the Sun
2861: Iron boils
1538: Iron melts
230: Paper catches fire
100: Water boils
58: Hottest weather on Earth
0: Water freezes
-39: Mercury freezes
-89: Coldest weather on Earth
-196: Air becomes liquid
-219: Air freezes
-270: Outer space
-273: Absolute zero

Absolute zero:
This is the lowest temperature possible, atoms have no kinetic energy and stop moving. It's impossible to get to -273 but you can get close. Very strange things happen within a millionth of a degree of absolute zero. Atoms lose their individuality and slide into each other, forming a single atom-sized "blob" - this is referred to as a state of matter known as "Bose-Einstein condensate".
