Where 5500 fits
Why 5500 is special
That is close to the Sun's surface temperature, and it is kept liquid in the outer core by pressure. The convection of that liquid iron generates the magnetic field that deflects solar wind.

Science
Earth's core approaches the Sun's surface temperature. The circulation of liquid iron there generates the magnetic field without which the atmosphere would be stripped by solar wind.
