English pronunciation [hy-PEER-ee-un]. Seeminly universal in astronomical sources; confirmed in Meridian/Crowell's Handbook of Classical Mythology (Tripp). [hy-PUR-ee-un] does not seem to be a variant. kwami
It would seem from the Greek that the adjectival form would be Hyperionian. Need to check if this is etymologically related to the musial term hyperionian. kwami 09:00, 2005 May 27 (UTC)
Hyperion's eccentricity
The eccentricity of Hyperion, stated above is only 0.0175. This is not high and is, in fact, only marginally higher than the earth's relatively low eccentricity of 0.0167. Whether the remaining conditions stated are still unique to Hyperion and sufficient to cause its chaotic rotation, I couldn't say.
68.5.190.105
- The eccentricity is in fact 0.123, so it is indeed relatively high.
