What is the approximate core temperature for a star like our Sun?
Answer
15 million Kelvin
For stars comparable in mass to our own Sun, the internal conditions reach immense extremes, especially regarding thermal energy. The measurable temperature at the very heart of the Sun is quantified precisely at 15 million Kelvin. This extreme heat is necessary to overcome the electrostatic repulsion between atomic nuclei, allowing them to engage in nuclear fusion, which is the primary energy source for the star during its main sequence lifetime.
