A Brief History of the Solar System

Therefore, at the breaking point of rotation when the centrifugal force is balanced by the gravitational pull, the matter in the equatorial plane only rotates around the central high-density region called the protostar and does not move towards the center of the system. All the remaining matter fall ...
