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

Enormous mass creates enormous pressure and heat, stars larger than the Sun do it even easier and as a result even though they have more hydrogen they last a shorter time than the Sun as they burn through the fuel quicker. https://youtu.be/vVE0B6g9F_0
