Amazing Saturn Photo Shows Tiny Titan
An astounding new photograph of Saturn shows just how small even its largest moon, Titan, is compare to the ringed planet's huge girth.
Titan seems inconsequential hovering to the right of the gas giant, spotted by the Cassini spacecraft.
There's two more moons in the shot - Prometheus and Pandora. Prometheus is the tiny white spot above the rings in the far upper right of the image.
Prometheus casts a shadow onto the planet, creating a black speck on the far left of the shot.
Pandora also casts a shadow across the south of the planet, beneath the rings.
