How does this theory fit the characteristics of the Solar System?
1. & 2. Collapse to a disk explains the concentration in the plane of the solar system, and why almost everything moves in the same direction.
3. The giant planets had disks of their own so their moons orbit in their equatorial plane
4a. Because the inner solar system was hot, only rock and metal could condense which resulted in terrestrial planets
4b. The outer solar system was cold enough for ices to condense and for hydrogen gas to be captured by a massive enough body. This resulted in Jovian planets.
4c. If an object in the outer solar system wasn’t massive enough to capture hydrogen gas, it remained as a small icy body. (Pluto, the outer planet moons, comets)
