Earth's Core Is As Hot As The Sun's Surface

Despite the extreme heat of Earth's core, reaching temperatures of approximately 5,200 Kelvin (about 9,392 °F or 5,200 °C), the planet's mantle and crust act as insulators, keeping the surface cool enough for life. The core's immense pressure also keeps its iron and nickel in a solid state.
