You stopped just short of actually answering the question by describing how the "non-random rotation of the solar nebula" actually causes the planets to rotate as they do. If your argument is that the randomly combining asteroids combine to the average, then on average the asteroids are rotating with the disk and the question then remains how did they come to rotate that way (on average). You just shifted the question to a different realm, but provided no answer. | |

| Feb 3, 2016 at 14:46 | comment | added | LocalFluff | That would be the most sane explanation, but still quite short. How does the rotation of the Solar nebula systematically affect each and every individual planet which is formed in it in the same way? Shouldn't half of the planets have been impacted in a way that tipped them over? | |

| Feb 3, 2016 at 14:30 | comment | added | LocalFluff | But the law of large numbers adds up to an average. Throwing planets like dice would add up to no planet rotation at all on average. Isn't it strange that the dice shows an even number of dots almost all of the time? If the rotation of the nebula affects the rotation of each planet, but not that of the asteroids, then I need more explanation to understand how that is so. Is there any relationship between the rotation of the Solar nebula, and the rotation of the individual planets formed within it? | |
