This image from the Cassini Spacecraft demonstrates the main difference between small moons and large ones. It’s all about the moon’s shape.
Moons like Tethys (660 miles or 1,062 kilometers across) are large enough that their own gravity is sufficient to overcome the material strength of the substances they are made of (mostly ice in the case of Tethys) and mold them into spherical shapes. But small moons like Janus (111 miles or 179 kilometers across) are not massive enough for their gravity to form them into a sphere. Janus and its like are left as irregularly shaped bodies.
Saturn’s narrow F ring and the outer edge of its A ring slice across the scene.
This view looks toward the unilluminated side of the rings from about 0.23 degrees below the ring plane. The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on October 27, 2015.
The view was obtained at a distance of approximately 593,000 miles (955,000 kilometers) from Janus. Image scale at Janus is 3.7 miles (6 kilometers) per pixel. Tethys was at a distance of 810,000 miles (1.3 million kilometers) for an image scale of 5 miles (8 kilometers) per pixel.

More Nasa lies, fake cgi s, Satanic ties, psychopaths of every sort, playing with little boys for sport, bow to the ball, the balls tell all, selling you a lie, making a haul, bubbles in water, bubbles in space, bubbles in the big old fish tank where it alllll takes place, wake from your slumber, wake from your sleep, my o my the #$%$ is getting deep, open your eyes, is it real, are you still, or are you spinning, it?s been known sense the beginning, Pedophile fraud scientists poisoning your brain! Don?t distain, don?t run with the insane, and live free on this glorious plane…
Pappi you forgot ur meds again
Janus and Tethys of Saturn’s moon could be explained like that but it is not true with Phobos and Deimos being the irregularly shaped moons of Mars. They seemed to be wanderers from asteroid belt nearby where the stones like them group together.Thank You.
