Humans could float in its sky
Titan’s thick atmosphere, low gravity
(less than our Moon) and reasonable surface pressure (1.45 times that of
Earth’s) mean that, by flapping a pair of wings strapped to your arms, you could fly in its skies with no more effort than walking.
We’ve landed on it, and we might again
The Saturn-orbiting spacecraft Cassini carried with it the Huygens probe, which landed on Titan (our only landing in the outer Solar System) on
14 January 2005. There are proposals being discussed for another landing, this time possibly using a boat.
It’s bigger than Mercury
Titan is beaten in size only by the Sun, the seven planets other than Mercury, and Jupiter’s Ganymede. It is over 5,000 kilometres (3,000 miles) wide, and is significantly more massive than all of
Saturn’s 61 other known moons combined.
It has a climate system like Earth
The liquids on Titan undergo a similar cycle to water here on Earth. Liquid methane evaporates from the surface, forming extremely thick clouds in the skies, before eventually raining down and replenishing the lakes and rivers on the ground.
It’s the only other world with liquid
Aside from Earth, Titan is the only world we know of that has liquids on its surface. These are in the form of lakes and rivers composed of liquid hydrocarbons including Ontario
Lacus, a lake about 240 kilometres (150 miles) long in Titan’s southern hemisphere.
