Which is hotter, the Sun or the inner core of the Earth?

Image caption The Earth's solid inner core is surrounded by a fast-moving liquid core, giving rise to the planet's magnetic field. New measurements suggest the Earth's inner core is far hotter than prior experiments suggested, putting it at 6,000C - as hot as the Sun's surface. read more

However, the sun’s core temperature can be as high as 27 million F. If one compares this to Earth’s core temperature of 10,800 degrees Fahrenheit, then the sun’s core temperature is much hotter than that of the Earth’s core. read more

New measurements suggest the Earth's inner core is far hotter than prior experiments suggested, putting it at 6,000C - as hot as the Sun's surface. The solid iron core is actually crystalline, surrounded by liquid. But the temperature at which that crystal can form had been a subject of long-running debate. read more

Extrapolating from that measurement, scientists estimated the boundary between Earth's inner and outer core is a searing 10,832 F, give or take about 930 degrees, at a pressure of 3.3 million atmospheres (or 3.3 million times the atmospheric pressure at sea level). read more
