Boiling point

The composition of jupiter is similar to that of the Sun - mostly hydrogen and helium. Deep in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid. 

This gives Jupiter the largest ocean in the solar system—an ocean made of hydrogen instead of water....

The moon of Saturn is circumvented since 2005 by astronomists. The moon has the size 1.19 times of Earth. It has a extreme temperature of -179°C. The planet contains dense clouds of liquid Methane which is deadly for any human.

But significantly 20%...

• Stars supports itself against its own gravity through the creation of thermal pressure.
• Inside every star, a huge amount of energy is being generated through nuclear reactions (fusion) which convert hydrogen into helium.
• Eventually, a star ...
