Saturn's moon Phoebe might be a planetesimal—a remnant of the rocky building blocks of the planets in our Solar System. A new study by Julie C. Castillo-Rogez et al. from Cassini spacecraft data ...

Phoebe was large enough to survive this turbulence. More than 60 moons are known to orbit Saturn, varying drastically in shape, size, surface age and origin.

New images made by the Cassini spacecraft during its fleeting encounter with Saturn’s moon Phoebe show a battered, pockmarked sphere that may be composed primarily of ice-rich material overlaid ...

Saturn's moon, Phoebe, is not an asteroid but a 4.5-billion-year-old primordial body from the solar system's outer reaches, Cassini mission scientists say.

Saturn and several of its moons appear in this image snapped by Cassini in 2007. The entire system, save one moon, appears to have water similar to that of Earth, which is unexpected based on our ...

Saturn has the most moons of any other planet in the solar system. Here, we explore some of the 274 moons that orbit the ringed planet.

The Cassini space probe will take the closest look yet at Saturn's dark, rough and contrary moon Phoebe when it flies past this weekend. Cassini will capture data on Phoebe on its way to a four ...

The debate about the origin of Saturn’s moon Phoebe is over. Although it may look like an asteroid, the tiny moon actually is an icy interloper from the fringes of the solar system, according to ...

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 ...

Images snapped by NASA’s Cassini spacecraft show that Saturn’s moon, Phoebe, is not an asteroid but a 4.5-billion-year-old primordial body from the solar system’s outer reaches.

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.
