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 in space is close to absolute zero because any object there will radiate heat until it cools to that point. This is for objects not exposed to direct sunlight. In Earth orbit, the temperature of objects in sunlight can rise to 120Â°C/ 250Â°F. The actual temperature in space is about 3Â°K (-270Â°C or three degrees Celsius above Absolute Zero). There are still molecules in space, just very few of them, and this is their temperature.
