Titan and Dione Via Cassini

Titan and Dione Via Cassini

The Cassini Spacecraft was able to take an impressive picture of Saturn’s moon Titan and Dione last May. The moons were captured from the spacecraft as it looked away from the planet. The larger body is Titan, and the smaller is Dione. The Rings of Saturn make for a very nice backdrop to the spectacle. (Image credit NASA / Cassini Imaging Team)

 

Titan

Titan is the largest moon of Saturn, the only natural satellite known to have a dense atmosphere, and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found.

Titan is the sixth ellipsoidal moon from Saturn. Frequently described as a planet-like moon, Titan has a diameter roughly 50% larger than Earth’s moon and is 80% more massive. It is the second-largest moon in the Solar System, after Jupiter’s moon Ganymede, and it is larger by volume than the smallest planet, Mercury, although only half as massive. Titan was the first known moon of Saturn, discovered in 1655 by the Dutch astronomer Christiaan Huygens, and was the fifth moon of a planet apart from the Earth to be discovered.
