“The Gasoline-Scented Moon: What Titan’s Hydrocarbons Reveal”

Saturn's moon Titan is rich in hydrocarbons, molecules made of hydrogen and carbon, such as methane and ethane. These hydrocarbons make up both Titan's dense orange atmosphere and its surface lakes. These same compounds are present in crude oil and gasoline on Earth, meaning that Titan theoretically has a scent that closely resembles petroleum or gasoline, if you were able to safely sniff it.

Scientists know all this thanks to the data collected during the Cassini-Huygens mission, which confirmed liquid methane and ethane in Titan's lakes and seas. Interestingly, they also mapped their behavior through spectral analysis. The conclusion is that Titan's lakes behave very much like Earth's ones, but with methane and ethane instead of water. The all-familiar evaporation, clouds, and rain cycle is present on Saturn's moon as well.

It's important to note that methane on its own is odorless. The gasoline-like smell is tied to the presence of heavier hydrocarbons, like benzene, that have a sweet, aromatic scent of solvents and fuel. So although we can't actually smell Titan, its chemical makeup suggests that a whiff would likely evoke the familiar tang of petroleum
