<<Aegaeon (Greek Αιγαίων), also Saturn LIII (provisional designation S/2008 S 1), is a natural satellite of Saturn. Its discovery was announced by Carolyn Porco of the Cassini Imaging Science Team on March 3, 2009, from observations taken on August 15, 2008.
Aegaeon orbits within the bright segment of Saturn's G Ring, and is probably a major source of the ring. Debris knocked off the moon forms a bright arc near the inner edge, which in turn spreads to form the rest of the ring. Aegaeon orbits in a 7:6 resonance with Mimas, which causes a ≈ 4-year oscillation of ≈ 4 km in its semi-major axis. Assuming it has the same albedo as Pallene, it is estimated to be half a kilometer in diameter. It orbits Saturn at an average distance of 167,500 km in 0.80812 days, at an inclination of 0.001° to Saturn's equator, with an eccentricity of 0.0002.
It is named after Ægæon, one of the hecatonchires. The Hecatonchires, or Hekatonkheires (Ἑκατόγχειρες) "Hundred-Handed Ones," Latinised Centimani), were figures in an archaic stage of Greek mythology, three giants of incredible strength and ferocity that surpassed that of all Titans whom they helped overthrow. Their name derives from the Greek ἑκατόν (hekaton; "hundred") and χείρ (kheir; "hand"), "each of them having a hundred hands and fifty heads." Hesiod's Theogony reports that the three Hekatonkheires became the guards of the gates of Tartarus.
According to Hesiod, the Hekatonkheires were children of Gaia (Earth) and Uranus (sky). Their names were Briareus (Βριάρεως) the Vigorous, also called Aigaion (Αἰγαίων), Latinised as Aegaeon, the "sea goat", Cottus (Κόττος) the Striker or the Furious, and Gyges (Γύγης) or Gyes (Γύης) the Big-Limbed. If some natural phenomena are symbolised by the Hekatoncheires then they may represent the gigantic forces of nature that appear in earthquakes and other convulsions or in the motion of sea waves.
Soon after they were born their father Uranus threw them into the depths of Tartarus because he saw them as hideous monsters. In some versions Uranus saw how ugly the Hekatonkheires were at their birth and pushed them back into Gaia's womb, upsetting Gaia greatly
, causing her great pain and setting into motion the overthrow of Uranus by Cronus (a.k.a, Saturn), who later imprisoned them in Tartarus. The Hekatonkheires remained there, guarded by the dragon Campe, until Zeus rescued them, advised by Gaia that they would serve as good allies against Cronus and the Titans. During the War of the Titans the Hekatonkheires threw rocks as big as mountains, one hundred at a time, at the Titans, overwhelming them.
Other accounts make Briareus or Aegaeon one of the assailants of Olympus, who, after his defeat, was buried under Mount Aetna. Briareus is mentioned in the Divine Comedy poem Inferno as one of the Giants in the Ninth Circle of Hell (Inferno XXXI.99). The giant is also mentioned in Cervantes' Don Quixote, in the famous episode of the windmills.>>
