Info Astronomi : Phoebe

Phoebe (pronounced /ˈfiːbiː/,^[5] or as Greek Φοίβη) is an irregular satellite of Saturn. It was discovered by William Henry Pickering on 17 March 1899 from photographic plates that had been taken starting on 16 August 1898 at Arequipa, Peru by DeLisle Stewart^{[6][7][8][9][10]}. It was the first satellite to be discovered photographically.

Phoebe was the first target encountered upon the arrival of Cassini–Huygens to the Saturn system in 2004, and is thus unusually well-studied for a natural satellite of its size. Cassini's trajectory to Saturn and time of arrival were specifically chosen to permit this flyby.^[11] After the encounter and its insertion orbit, Cassini would not go much beyond the orbit of Iapetus.

he moon is named after Phoebe^[8], a Titan in Greek mythology. It is also designated Saturn IX. TheIAU nomenclature standards have stated that features on Phoebe are to be named after characters in the Greek myth of Jason and the Argonauts. In 2005, the IAU officially named 24 craters^[12] (Acastus, Admetus, Amphion, Butes, Calais, Canthus, Clytius, Erginus, Euphemus, Eurydamas, Eurytion, Eurytus, Hylas, Idmon, Iphitus, Jason, Mopsus, Nauplius, Oileus, Peleus, Phlias, Talaus, Telamon, and Zetes).

Dr. Toby Owen of the University of Hawaii at Manoa, chairman of the International Astronomical UnionOuter Solar System Task Group said

"We picked the legend of the Argonauts for Phoebe as it has some resonance with the exploration of the Saturn system by Cassini-Huygens. We can't say that our participating scientists include heroes like Hercules and Atalanta, but they do represent a wide, international spectrum of outstanding people who were willing to take the risk of joining this voyage to a distant realm in hopes of bringing back a grand prize."
