Mainly hydrogen, with small of helium, ammonia, methane and other trace gasses. Also, a lot of dust.
Some of the hydrogen may be primordial, remnants from the Big Bang that we believe created the universe. But all of the heavier elements (and some of the hydrogen) are the remnants of old supernova explosions, the ejecta from the destruction of the original stars.
Asteroids are solid rocky objects. Gas giants, like Jupiter and Saturn, are mainly composed of gas.

It is composed completely of gas. 82% hydrogen & 18% helium
Earth's atmosphere is composed mainly of nitrogen.
These are the four outer planets, known as the gas giants. Jupiter, Saturn, Uranus and Neptune.

Fossil fuels are mainly composed of carbon and hydrogen. These elements make up the hydrocarbons found in fossil fuels like coal, oil, and natural gas.

The first gas planet in our solar system is Jupiter. It is the largest planet and is composed mainly of hydrogen and helium.
Comets are mainly composed of ice, dust, and gas, and they often orbit the sun in elongated, elliptical paths. When a comet gets closer to the sun, the heat causes the ice to vaporize, releasing gas and dust particles that form a glowing coma and a tail.
Natural gas is mainly composed of methane, a hydrocarbon compound with a chemical formula of CH4. In addition to methane, natural gas can also contain small amounts of other hydrocarbons such as ethane, propane, and butane, as well as non-hydrocarbon gases like carbon dioxide, nitrogen, and hydrogen sulfide.
