Why is the sun able to undergo fusion so easily, compared to us?

Question

I’ve read maybe it has something to do with gravity…? But we have gravity here on earth too.

And while the sun’s internal temperature is around 15M degrees celsius, apparently for us to replicate the fusion effect here on Earth, we need to superheat atoms to 100M degrees celsius. Why the difference?

Answer 1

The only difference I get is that the sun does not have the need to contain the reaction (and thus the high temperatures) since it’s itself the reaction, and also it has gravity like us but its is way stronger. Otherwise we need to contain that stuff since that temperatures can destroy anything, any material, so it a bit more complicated. We need to create sophisticated and strong magnetic fields since it’s our only way to contain that stuff at those temperatures.
