5 days ago· Solar system - Formation, Outer Planets, Moons: This general scheme of planet formation—the building up of larger masses by the accretion of smaller ones—occurred in the outer solar system as well. Here, however, the accretion of icy planetesimals produced objects with masses 10 times that of Earth, sufficient to cause the gravitational collapse of the

Solar System Formation

May 1, 2024· II. How did the Solar System form? The formation of the Solar System is believed to have begun about 4.6 billion years ago from a giant cloud of gas and dust known as the solar nebula. This cloud collapsed under its own gravity, causing it to spin and flatten into a disk shape.

The origin of the Solar System

The small blobs would have higher rotation than is seen in the planets of the Solar System, but the theory accounts for this by having the ''planetary blobs'' split into planets and satellites. However, it is not clear how the planets came to be confined to a plane or why their rotations are in the same sense.
