Great question 934cmte47, 497cmte47 + 877cmte47!
The Sun is about 6000 degrees celsius on its surface ☀ this is about 30 times hotter than the inside of the oven when you cook food in it ? ? ? (**but do not touch the inside of the oven to investigate this as it will burn you!**).
There are loads of chemical reactions taking place in the Sun that give out heat ? – this process is called “nuclear fusion”. It’s similar, but not quite the same, as what happens in nuclear power stations (this is actually “nuclear fission” ?). These reactions are what keep the Sun “burning” ?

Great question guys! On the sun there are atoms of hydrogen smashing into each other and sticking together to make helium atoms. That’s called nuclear fusion and gives out lots of energy as heat. That is actually how all the elements were made – from smaller atoms smashing into each other and making new elements! Luckily we’re quite a long way away from the Sun otherwise our planet would be much hotter, like on Mercury and Venus. In the daytime on Mercury the temperature can be as hot as 427 degrees Celsius because it so much closer to the Sun!
