text: Whereas the Earth has a core which is 55% of its overall radius and Venus must have a core fairly close to that (certainly no less than 50% or more than 60% of the overall radius), Mars may well have a core less than a third the size of the planet, and Mercury's core is probably 70 to 80% of the size of the planet.
