Eli5: How are planets formed?

644 views

I understand that planets are essentially space rock that got together and made what we know today as planets, I’m simplifying this a lot but let’s go with it. What I want to know is how those space rocks are formed and then put together to make planets? Where did the rock come from? Is it elements clashing together millions of times over until they form what we know today as space rocks?

The atoms from an exploding supernova create the debris for a planet to form atoms heavier than iron require a supernova without one all you get are gas giants.
