The Sun is a huge mass of hydrogen and helium gas. It is such a huge mass of those gases that the weight of the gases pressing down on each other have turned them into liquid hydrogen and liquid helium. There is so much weight and pressure, in fact, that the core of the Sun is almost a metallic form of liquid hydrogen. The intense
pressure causes heat and lots of it. The intense pressure and unbelieveable heat are causing a fusion of hydrogen into helium which is a nuclear process. That nuclear fusion gives off large amounts of heat and radiation.
The surface of the Sun is most likely molten hydrogen gas liquid.

Hello
When it comes to compelling evidence of a solid surface on the sun, seeing is believing. It is said that a picture is worth a thousand words. Go to the following website which shows pictures of the sun from Nasa along with explanations to what your looking at :-

The sun IS solid but the Sun's outer visible layer is called the photosphere and has a temperature of 6,000°C (11,000°F). This layer has a mottled appearance due to the turbulent eruptions of energy at the surface.

No. The Sun is mostly hydrogen and helium, all in a big, open fusion nuclear reaction. We see some of the tremendous radiation given off from the sun as visible light, and are shielded from the worst radiation by Earth's magnetic field.

The sun is not a solid but is made up of gases for it is a star.

Actually the sun is a gas. It is composed of mostly hydrogen and helium and heal together by heat and nuclear reactions. Although it appears to be a solid, its a big ball of fire.

The sun is not solid, liquid, or gas. It is the fourth state of matter: plasma.
It's rather incredible that not one single person has correctly identified this yet.

No, it is gas. Helium at the core, hydrogen doward the surface. The average light proton takes 100,000,000 years to go from the center to the surface because of the gravitational force of whatever is at the center of the sun.
It is basically a giant thermal nuclear reaction that has unlimited fuel, for now.

The Sun is mostly hydrogen and helium, but also contains wery small quantities of lots of other elements.
Traces of the other elements such as oxygen, magnesium and iron give us the clues we need to find out what the solar atmosphere is like.

It is not solid. It is pure gas. 70% hydrogen, 28% helium, less than 2 % metallic matter.
