The Earthâs Centre is 1000 Degrees Hotter than Previously Thought. Scientists have determined the temperature near the Earthâs centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago.he layers of the Earth and their temperatures: crust, upper and lower mantle, outer core and solid iron core. Credit ESRF. The Earthâs core consists mainly of a sphere of liquid iron at temperatures above 4000 degrees and pressures of more than 1.3 million atmospheres.
The temperature at the very center of the Sun is about 15,000,000Â° C (27,000,000Â° F) and the density is about 150 g/cmÂ³ (approximately 10 times the density of gold, 19.3 g/cmÂ³ or lead, 11.3 g/cmÂ³). Both the temperature and the density decrease as one moves outward from the center of the Sun. The nuclear burning is almost completely shut off beyond the outer edge of the core (about 25% of the distance to the surface or 175,000 km from the center).
