There are lots of places in our Universe where it’s much hotter than the Sun.
Our Sun is a giant ball of gas that is 6000 degrees Celsius at the surface and millions of degrees in the centre. That is very hot! A kettle of boiling water is scalding hot and it’s “only” 100 degrees Celsius.
Our Sun gets so hot because the gas inside burns in a special way that turns some of the gas into lots of energy.
The Sun is a star – and the stars of the night sky are Suns a bit like our own. Some stars are much bigger than our Sun (and weigh a lot more too), and are even hotter inside. In some cases it’s hundreds of millions of degrees inside the star!
The only reason stars don’t explode straight away is that they are so heavy that the force of gravity keeps the star together. In the same way, our Sun’s own gravity holds it together in a nice steady way for a very long time – billions of years. Lucky for us.
For stars that are heavier than our Sun, the gas inside burns a lot quicker and can suddenly run out of energy. The inner part of the star falls towards the star’s centre because of gravity. The outer part of the star first falls inwards too, but bounces off into space. This spectacular event is called a supernova, and can produce temperatures of millions of degrees.
