Titan, Sanigrah ke chaand me se sab se barraa hae aur ii Saur Mandal ke duusra sab se barraa chaand hae. Ii khaali ek jaana jaae waala chaand hae jiske atmosphere, dunia ke atmosphere se denser hae, aur outer space me, dunia ke alaawa, khaali ek jagha hae jahaan pe stable bodies of liquid ke rahe ke sabuut hae. Titan, Sanigrah ke saat golaa chaand me se ek hae aur duusra sab se duur hae. Titan ke diameter, dunia ke chaand se 50% jaada hae aur 80% jaada garrhu hae. Ii saur mandal me, Jupiter ke chaand, Ganymede, baad, duusra sab se barraa chaand hae, aur Mercury se barraa hae; lekin Titan ke wajan Mercury ke khaali 40% hae, kaaheki Mercury me jaada loha aur patthar hae, jab Titan jaada kar ke ice hae, jon kamti dense hae.

  4. "Titanian" is the written adjectival form of both Titan and Uranus's moon Titania. However, Uranus's moon has a Shakespearean pronunciation with a short "i" vowel and the "a" of spa: /tɪˈtɑːniən/, while either spelling for Titan is pronounced with those two vowels long: /tˈtniən/.
