The metallic core of Ganymede suggests a greater heat at some time in its past than had previously been proposed.

Mercury in the Solar System has a metallic core equal to 60-70% of its planetary mass.

At even greater depths, the rock may give way to a metallic core.

Psyche appears to be a case of an exposed metallic core from a bigger differentiated parent body.

The implication is that Ganymede has a molten metallic core.

This was a small, light world, lacking Earth's dense metallic core, but if you went deep enough, you would still meet huge pressures.

This process can form a stony or metallic core, surrounded by a mantle and an outer surface.

The remaining rocky or metallic core would resemble a terrestrial planet in many respects.

The metallic core makes up approximately 20% of Io's mass.

The interior of Mercury is believed to contain a large metallic core, which would account for the planet's high density.
