Earth's Core is Hotter Than the Sun

Really! The Earth's core is hotter than the outer layer of the Sun.

The Sun's huge boiling convection cells, in the outer visible layer, called the photosphere, have a temperature of 5,500°C.

The Earth's core temperature is about 6100ºC. The inner core, under huge pressure, is solid and may be a single immense iron crystal. The outer core is liquid, and probably acts as a dynamo creating our magnetic field.

But before you get the wrong impression, keep in mind that the core of the Sun is a broiling 15,000,000ºC. That's enough to vaporize rocks in a comet that gets too close, and enough to give you a nasty burn 93,000,000 million miles away after just a few minutes exposure when you're sun bathing.
