Universe sandbox 2 creating a solar system
In there, select the number of bodies.Do not choose 250.000 bodies -) Then let it run and see what happens.Įdit: Just tried a 2-4 radius ring around the sun with 500 bodies and that dense (all things relative) a ring, with that much relative velocity, does actually quickly enough show accretion.
Choose one of the preset types and click the little pencil icon bottom right on the ring icon. If you want to run this test, I suggest turning off fragmentation, placing a star and then using the ring tool to create the bodies. The latter can be handled by simply turning off fragmentation, though, in which case all collisions are just merging, so.
If, however, you scatter just a few thousand bodies in orbit around a star, the odds of any two bodies moving close enough to collide is rather low (small objects and large space) and the odds of this happening at a relative velocity which is low enough to not just disintegrate them are no better. They will attract and collide and grow into a larger body. no relative velocity) moon in it and then continuously placing more still moons. It can work, which can be seen by making a new simulation and placing a still (i.e.
