Titan Quiz – Methane Lakes on Saturn's Largest Moon

Titan, discovered by Christiaan Huygens in 1655, is Saturn's largest moon and the second-largest moon in the solar system, larger than the planet Mercury. It is the only moon with a thick atmosphere, mostly nitrogen, with a surface pressure higher than Earth's.

At about minus 179 degrees Celsius, Titan has a methane cycle with clouds, rain and rivers. Lakes and seas of liquid methane and ethane, including Kraken Mare and Ligeia Mare, lie near the poles, mapped by Cassini's radar.

In 2005 the European Huygens probe, carried by Cassini, landed on Titan, the most distant landing ever. NASA's Dragonfly rotorcraft is planned to fly across its surface in the 2030s.
