Using concepts of solar system, Hydrogen, Helium and many other gases are the parts of the galaxy that lies inside the sun's orbit .

The Sun has many regions. The interior regions include the core, radiative zone, and the convection zone. When we move outward – the visible surface or photosphere is next, then the chromosphere, after that transition zone, and then the corona – the Sun’s expansive outer atmosphere.

The core is the most hottest part of the Sun. Nuclear reactions here – where hydrogen is fused to form helium element – power the Sun’s heat and light. Temperatures top to 27 million °F (15 million °C) and it’s about 86,000 miles (138,000 kilometers) thick. The density of the Sun’s core is about 150 grams/[tex]cm^{3}[/tex](g/cm³). That is of approximately 8 times the density of gold (19.3 g/cm³) or equal to 13 times the density of lead (11.3 g/cm³).

Hence, Gases(Hydrogen and helium majorly) forms the composition of part of galaxy that lies inside the sun`s orbit.
