What could the chemical composition of the planets have to do with observations of their inertia? How could that matter other than by their mass?

- jessriedel 2y agoI think the idea is that if they have the same chemical composition this is good evidence that they formed from the same primordial gas cloud. If they just happened to be passing by each other, there would be no reason for the composition to be so similar.
