Anaxagoras' original description of the Earth and Moon as 'Stone Stars', or stones hurled from the molten Sun and cooled to a solid state ( see: The Stone Star ) may have been prophetic in its time, but a star is not a large version of a planet's molten interior.

'Sol' exists, as all stars do, in a plasmatic state. Plasma has properties quite unlike those of solids, liquids, or gases and is considered to be a distinct state of matter. Plasma typically takes the form of neutral gas-like clouds. Like gas, plasma does not have a definite shape or a definite volume unless enclosed in a container. Unlike gas, in the influence of a magnetic field, it may form structures such as filaments, beams and double layers.

The Sun is both a plasma and a gas. It is not a liquid.
