How hot is it at the Earth's centre?

What temperature is it at the Earth's core? And how do we know?

If memory serves me correctly, I read somewhere an estimate of 13,000 degrees (F? C?). Could not give you the reference, however.

Did someone poke an oversized one of these in the ground?


OK, I'll shut up now.

Indeed; how do they know?

I found a reference the other day suggesting the Earth's core is at about 5700K.

It is estimated at 5,700 K (5,430 C; 9,800 F).

This is found by calculating the melting temperature of impure iron at the pressure of the inner core boundary.
