Other interesting characteristics:

  • One Titan year is equal to 30 Earth Years
  • Both Titan and Earth have a greenhouse effect
  • It is believed that Titan also has continents and oceans as determined through radar
  • Second largest moon in our Solar System (Jupiter's Ganymede is the largest)
