First of all, burning requires the presence of oxygen, which is not much available in outer space. Also, burning / combustion is generally endothermic process and it requires heat.
The giant outer planets Jupiter, Saturn, Uranus, and Neptune have extremely thick atmospheres of hydrogen, helium, methane, and ammonia. Titan, the moon of Saturnalso has a methane-ammonia atmosphere.
The atmosphere of Titan is mostly nitrogen with a small percentage of methane and hydrogen.
The two planets that are mostly composed of methane and nitrogen are Uranus and Neptune. These gas giants have thick atmospheres made up primarily of methane and nitrogen, with smaller amounts of other gases such as hydrogen and helium.
Methane clouds are primarily found in the atmospheres of two planets in our solar system: Titan, Saturn's largest moon, and Neptune, the eighth planet from the Sun. Titan has a thick atmosphere rich in nitrogen and methane, leading to the formation of methane clouds and liquid methane lakes. Neptune's atmosphere also contains methane, which contributes to its blue color and can form clouds in its dynamic weather system.
Hydrogen and helium mostly, some ammonia and methane too though.

No, Titan is made out of methane.
No. It rains methane on Titan.
The most abundant gas in Titan's atmosphere is nitrogen, making up about 95% of its composition. Other components include methane and hydrogen.
Titan has a dense atmosphere primarily composed of nitrogen, with small amounts of methane and other gases but very little oxygen. The lack of oxygen on Titan's surface makes it inhospitable to humans and most known forms of life as we know it.
Saturn is approximately 75% hydrogen and 25% helium with traces of other substances like methane and water ice.The composition of Saturn's atmosphere is that it contains mainly hydrogen and some helium.
Venus and Titan are two planets in our solar system that have hydrocarbon smog. Venus's thick atmosphere is composed of carbon dioxide and sulfuric acid clouds, while Titan's atmosphere contains nitrogen and methane, forming a haze of organic aerosols.
