  1. According to NASA, the centre of the sun is almost 18 million degrees Celcius.

    As for HOW we know this. We can measure the radius of the sun and we can also have a good estimate of its mass, using physical laws, we can then approximate the temperature. NASA has a more detailed discussion on its website
