- Is there a good reason why it is assumed that rocky planets only form in protoplanetary discs?
After googling for many hours I am still not understanding why the formation of rocky planets shall be restricted to protoplanetary discs.
Why can't they form from dustclouds far away from any star? Agglomeration should still happen over time. Jeans criterium should not play a role since it is not relevant for the formation of rocky planets in a protoplanetary discs.
So, can somebody explain what I am missing out?
