Terrestial Planets internal en - Planetary core

The planetary core consists of the innermost layer(s) of a planet. The core may be composed of solid and liquid layers. The cores of Mars and Venus may be completely solid as they lack an internally generated magnetic field. In our solar system, core size can range from about 20% to 85% of a planet’s radius. 50x40pxThis section needs additional citations for verification.
