The Sun's composition is based on the currently assumed composition of the giant planets [closed]

I posit that the giant planets comprise methane gas hydrate (CH4)8(H2O)46). If so, would not the Sun have to have a large composition of oxygen?

• Its not really clear what you are asking. Can you explain your assertion that the giant planets comprise of methane hydrate. Then explain how this links to the sun, and what you mean by "large". The composition of the sun is quite well known from spectroscopic and modelling data, and it is mostly H and He with small amounts of other elements. – James K Jun 22 '18 at 20:38
• You state "The Sun's composition is based on the currently assumed composition of the giant planets". This is not correct. The abundances of different elements in the sun is estimated from a variety of data sources. I'm not an expert in this topic, but I don't think that the composition of the gas giants is a significant factor used to determine solar abundances. – Dr Chuck Jun 23 '18 at 9:40

Oxygen is the third most abundant element in the Sun, hydrogen and helium being first and second. Most sources estimate solar oxygen abundance between 0.6% and 1.0% by mass. The astronomical literature expresses element abundance as a logarithm of atom count relative to hydrogen: $$A(x) = \log{n(x)\over{n(\mathrm{H})}} + 12$$ Lodders 2010, based on several contemporary studies, recommends a photospheric oxygen abundance value $A(\mathrm{O})$ = 8.73 $\pm$ 0.07, or 0.046% to 0.063% as many oxygen atoms as hydrogen atoms.
