During my research on a better comprehension of the formation of our planetary system, which started with my paper “Are Venus’ and Uranus’ Tilt of Natural Origin?”, it appeared to me that the protuberance-model needs an addition. As know from my former paper, Neptune is the “lonely planet”. But I found more. In this paper, I come to the curiosum, that the sequence order of the gas-planets, at the very beginning of its existence as proto-planets, should have been as follows: proto-Jupiter, -Neptune (!), -Saturn, and -Uranus. The basis for this research lays in the existence of the remarkable Titius-Bode law, and the unexpected successive matter composition of our gas-planets.
