Here is a cartoon of the standard model. |
![]() |
  some of the remaining gas condenses into dust, |
  dust forms grains of sand, and |
  grains of sand form rocks. |
  The rocks collide and stick together to form larger rocks. |
  Eventually some heaps of rocks get massive enough to gravitationally attract other stuff, |
  and these growing rock piles form planets. |
