Titan is Saturn’s largest moon, even bigger than Mercury, making it one of the most massive moons in our entire solar system.

It’s completely unique because it has a thick, hazy orange atmosphere, unlike any other moon — and even thicker than Earth’s.

The surface is extremely cold, around -179°C, so water there is frozen as hard as rock, and life would need to be wildly adapted.

Titan has lakes, rivers, and even rain, but instead of water, they’re made from liquid methane and ethane, like alien gasoline.

There’s an underground ocean beneath its icy shell, probably made of salty water — scientists think it might support alien life.

The landscape looks strangely Earth-like, with mountains, dunes, and maybe icy volcanoes that shoot out cold slush.

Titan's atmosphere is mostly nitrogen, like Earth’s, but filled with methane clouds and toxic gases that would choke a human instantly.

It has seasons and weather because Saturn tilts on its axis, meaning Titan’s skies actually change through the year.

Titan was visited by the Huygens probe in 2005, which landed on the surface and sent back the first-ever photos from this alien world.

Because of its atmosphere, chemistry, and possible ocean, Titan is one of the top places in the solar system to search for life beyond Earth.
