I am going to try to convince you that:
- The 4 giant planets formed within 15AU or 20AU of the Sun.
- Beyond them was a massive disk that extended to ~30AU.
- The 4 giant planets slowly spread due to leakage from this disk.
- Jupiter and Saturn crossed the 1:2 mean motion resonance at 700Myr
- Uranus and Neptune went unstable and scattered into the disk.
- Thereby produced the lunar Late Heavy Bombardment and Trojan asteroids.
- Uranus and Neptune evolve onto current orbits due to interactions with the disk.
- This pushes out the Kuiper belt.
5AU
10AU
15AU
30AU
And everyone lived happy ever after.
