It seems NASA has been busy studying the Sun with the latest technology and imagery enhancement to conclude that the solid sun is comprised of a calcium-ferrite core 4,500 km underneath the photosphere as described in great detail here. There you can read all the latest knowledge we have of the sun.
Calcium ferrite is a compound of Ca(FeO2)2 and has a boiling point of 100 degrees Celsius, and a molecular weight of ~215.77. Density estimates range from 2 to 3.3 gm/c3 (published here).
The density of the Sun is about 1.4 gm/cm3. This is half the density of it’s interpreted mineralogy and chemistry and supports the electric-gravity theory.
Given the boiling point of calcium-ferrite of 100 Degrees Celsius, one suspects a lot more work needs to be done to figure out what the Sun is actually made of chemically and mineralogically, but one thing it certainly isn’t is a hot ball of hydrogen and helium, and nor does it host a core of a neutron star, another one of the impossible things many seem to believe in before breakfast.
