TITAN : SATELLITE VI OF SATURN
Titan (Saturn VI) was discovered by Huygens in 1655. Its revolution period is 16 days.
Titan has an opaque atmosphere that prevents us from perceiving the ground. Atmospheric pressure on the ground should be 1.5 bar (1.5 times Earth's atmospheric pressure at sea level).
