This panel of images shows the nearly spherical shape of Saturn’s moon Phoebe, as derived from imaging obtained from NASA’s Cassini spacecraft. Each image represents a 90-degree turn.

Phoebe's physical properties, as well as its odd orbital characteristics, led the authors to conclude that the moon formed in the Kuiper Belt region, making it a cousin to Pluto.

A giant ring around Saturn is even larger than thought, spanning an area of space nearly 7,000 times larger than Saturn itself, researchers say. "We knew it was the biggest ring, but now we find ...

Saturn’s moon Phoebe seems to be the system’s oddball; it likely didn’t form in place, but was captured after forming much farther out in the solar system. NASA/JPL. One oddball.

When it comes to Saturn’s moons, Phoebe tends to be overshadowed by its siblings. Titan‘s size earns her the title of Saturn’s biggest moon (and the second-biggest moon in our solar system ...
