The sun's "atmosphere" or corona is primarily composed of Hydrogen and some Helium. The Sun produces helium by the process of nuclear fusion in it's core. Meaning that it compresses hydrogen under great heat and pressure until the nucleus of two atoms combine to make Helium. This is what fuels the Sun. The heated hydrogen and helium rise to the surface of the sun where they give off their heat. This process will continue until the sun runs out of Hydrogen. Then it will begin to produce heavier elements like carbon.
Any atmosphere by definition is made of gas.
No. As the name gas giant implies, these planets are made largely of gas. They have extremely thick atmospheres.
All planets in our solar system made of gas except for Mercury. Mercury is a terrestrial planet, composed mainly of rock and metal, with a very thin atmosphere.
An atmosphere is a layer of gas that is part of a planet, and usually surrounds it solid part, if there is a solid part. so for each planet, there is one and only one plant in its atmosphere. The earth is the only planet in the Earth's atmosphere; Mars is the only plant in the Martian atmosphere; etc.,
Mars and Venus, I guess you could call them our sisters gone wrong.

Most planets are made of some kind of terrain and atmosphere. Most planets in our solar system have a terrain that consists of some kind of rock, ice, sand, or dirt that forms the planet and an atmosphere that consists of a gas.
The four outer gas giants.
Gas giants are planets whose atmosphere is predominantly composed of gases, such as hydrogen and helium. These planets have a small solid core surrounded by thick layers of gas. Examples of gas giants in our solar system include Jupiter and Saturn.
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
While terrestrial planets are made of rock and have gases in the atmosphere, jovian planets are made almost entirly of gases. If an atmosphere is made of gases in a planet, then the atmosphere of the planets with more gases will be thicker.
The planets' own gravity has made them spherical. Also there are other effects such as their ability to retain an atmosphere, etc. The Sun's gravitycauses the orbits of the planets.
Jupiter and Saturn are mostly made of atmosphere, with Jupiter's atmosphere consisting mostly of hydrogen and helium, while Saturn's atmosphere is also primarily composed of hydrogen and helium, with traces of other elements.
