Phoebe (moon) - Wikipedia
For more than 100 years, Phoebe was Saturn's outermost known moon, until the discovery of several smaller moons in 2000. Phoebe is almost 4 times more distant from Saturn than its nearest major neighbor (Iapetus), and is substantially larger than any of the other moons orbiting planets at comparable distances.
Phoebe - NASA Science
Phoebe is one of Saturn's most intriguing moons, orbiting at a distance of 8,049,668 miles (12,952,000 kilometers) from the planet, almost four times the distance from Saturn than its nearest neighbor, the moon Iapetus.
Phoebe Moon Facts: The Largest Irregular Moon of Saturn
The dark moon Phoebe is the most studied irregular moon of Saturn. It has a mysterious origin as it may be an object from the Kuiper belt that got captured by Saturn’s gravity. Measuring roughly 213 km (132 miles) across, it is the largest irregular moon in the Saturnian system.
Phoebe (moon) - Simple English Wikipedia, the free encyclopedia
Phoebe is a moon which goes around (orbits) the planet called Saturn. It takes eighteen months for Phoebe to go all the way around Saturn. It is half made out of rock, and half made out of ice. The ground on Phoebe is black, which means that it is very dark when seen from Earth. Phoebe does not have any air, and there is no water on its surface.

Phoebe, midsize irregular moon of Saturn, discovered by the American astronomer William Henry Pickering in 1899 on photographic plates and named for a Titan in Greek mythology. Roughly spherical and about 210 km (130 miles) in diameter, Phoebe has a mean distance from Saturn of about 12,952,000 km
125 Years Since the Discovery of Saturn's Mysterious Moon
On August 16, 1898, DeLisle Stewart, an employee of the Arequipa Observatory, took a photograph of Saturn. Unbeknownst to him, this image captured an unknown moon of the planet, which would later be named Phoebe.
The True Shape of Phoebe - NASA Science
2004年12月17日 · A digitally rendered shape model of Phoebe was constructed using Cassini imaging data obtained before and after the spacecraft's close flyby of the Saturnian moon on June 11, 2004. The average diameter of Phoebe is about 214 kilometers (133 miles).

2005年5月27日 · Data from the NASA/ESA/ASI Cassini-Huygens mission are providing convincing evidence that Saturn’s moon Phoebe was formed elsewhere in the Solar System, and was only later caught by the planet's gravitational pull.
Phoebe - NASA Science
2004年12月17日 · Phoebe orbits Saturn close to the ecliptic (the plane in which Earth and most other planets orbit the Sun), rather than in Saturn's equatorial plane as the other Saturn satellites do. And Phoebe's orbit is retrograde -- in the direction opposite to that of the other satellites.
Cassini Finds Saturn Moon has Planet-Like Qualities
2012年4月26日 · PASADENA, Calif. -- Data from NASA's Cassini mission reveal Saturn's moon Phoebe has more planet-like qualities than previously thought. Scientists had their first close-up look at Phoebe when Cassini began exploring the Saturn system in 2004.
