If in case you are not familiar with Titan yet, this is one of the moons that orbit Saturn. Titan is known to be the 2nd largest moon in the solar system. It is often compared to earth because some scientists say that it is beginning to show some signs of life. The distance of the earth from Titan is at 1.4 billion kilometers.
It is evident that Titan is very far away from the sun so it makes people wonder if it is able to get enough life in order to possibly sustain life in the long run. The spacecraft that tried to reach Titan usually take about 6 years or more in order to get there.
