      Good question- I had to look it up to double check! The Earth’s core is made from a mixture of iron and nickel, and some of it (the outer core) is molten. For that to be the case, it has to be hotter than the melting point of iron. Some scientists have apparently recently calculated that to be around 6000 degrees celcius, hotter than the surface of the sun!

      The Earth’s core is the same temperature (more or less) than the surface of the sun. It’s 6000 degrees Celsius, which is very roughly the same temperature as the surface of the Sun.

      Naturally the Sun’s core is much hotter, venturing into millions of degrees .
      Despite being this temperature, barely any of the temperature on the surface we feel is due to the core… It’s all down to the massive amounts of radiation coming from the Sun.
