You have a star nearby, you have lots of free energy -- the hard part is arranging for the energy to be in the right place doing something useful. Hence treating it as a generic energy handling budget problem. | |

This is why planets will self assemble in the right situation. All you need to do is fly to the asteroid belt and do something to slow asteroids down. This will cause them to fall towards the sun. If done right, they will assume a new lower orbit at the location you want your planet. If you get them close enough to each other, they will clump together. Keep going and eventually the clump will have enough total gravity to reshape the material into a sphere and, viola, you have a planet. | |
