I guess that could work? Earth is actually the densest planet in the solar system so our baseline mass > size ratio might actually be a bit abnormal.

I was sure you were bullshitting, but no. Its true.
Iron and nickel core + enough mass for gravity to start compress the planed and we are just little more dense than Mercury.

Our core is also just huge, the outer core is larger than the moon and mercury.
