What may be inferred about other planetary bodies in our solar system?
Although we can infer that Earth and the other planetary bodies were created from the primordial accretion disc, we do not know if they were created at the same time.
Because of the different amount of metallic iron in the cores of the Moon and the other planetary bodies, we know that they were not created by the same process.
Since we know that the Moon and the other planetary bodies have noticeably different amounts of metallic iron in their cores, they cannot be made of the same materials.
The lack of metallic iron in the Moon's core weakens the theory that it was created from the primordial accretion disc. Therefore, the abundance of iron in other planetary bodies passage may suggest they were created from the primordial accretion disc.
The passage mentions a hypothesis of the creation of the solar system, which contains these planetary bodies, so it can be inferred that scientists do have some clue about it.
