Titan and Earth have many similar functions.
Just like the surface of the oceans on Earth is at what we & # 39; sea level & # 39; the seas of Titan are also at an average height.
It is currently the only other world we know of in our solar system with stable liquid on the surface.
Smaller lakes on Titan appear at altitudes hundreds of meters higher than the sea level of Titan. This is comparable to lakes found at high altitudes on Earth.
For example, the highest lake in the world navigable by large ships, Lake Titicaca, is more than 12,000 feet [3,700 meters] above sea level.
Titan's liquid bodies seem to be connected below the surface by something that looks like an aquifer on Earth.
Hydrocarbons flow below the surface of the Titan, similar to the way water flows through underground porous rock or gravel on earth.
This means that nearby lakes communicate with each other and share a common fluid level.
Apart from the earth, Titan is the only place in the solar system that is known to have rivers, rainfall and seas – and possibly even waterfalls.
Of course, in the case of Titan, these are liquid methane instead of water on Earth.
Normal soil-water, H2O, is frozen frozen on Titan, the surface temperature being -180 ° C (-292 ° F).
With its thick atmosphere and organic-rich chemistry, Titan looks like a frozen version of the Earth a few billion years ago, before life began to pump oxygen into our atmosphere.
Because Titan is smaller than the earth, gravity does not hold its gas envelope so tightly that the atmosphere extends over 595 km in space.
With Titan's low gravity and dense atmosphere, methane raindrops could become twice as large as earth's raindrops.
