Scientists suspect that of the well known planets that Jupiter has a solid core that is large in size. It has been discovered that Jupiter contains a core that includes rock and hydrogen metals, but scientists are unsure if deep within the planet contains a true solid core. Of all the nine planets, Jupiter's core contains the most "solid" case for a true solid core.

Terrestrial and Gas Giant planets both have iron cores. One way to prove this theory is because all of these planets have or had a magnetic field at some point in their lives.

However, the inner planets, Earth, Venus, and Mercury at least, have molten nickel-iron cores.

Another viewpoint: Scientists still don't know for sure that the gas giants have cores. The magnetic fields of the gas giants are not thought to be caused by iron. For example Jupiter's is believed to be caused by "liquid metallic hydrogen"

All the terrestrial planets are believed to have iron in their cores. Earth definitely has a solid nickel-iron inner core with a liquid nickel-iron outer core.

The extent to which the other inner planets have solid or liquid metallic cores is still uncertain.
