Fictional info (?) |
Suggested name | Hwahye-yyang |
Planet type | Huge cold gas giant |
For this reason, scientists often classify Hwahye-yyang and Wuze Heiz Wen as "huge cold gas giants" to distinguish them from the other planets. It is named after the deity Hwahye-yyang, the demon of the underworld.
As seen relative to the fixed stars, it rotates on its axis exactly four times for every four revolutions it makes around RIK 72.
As one of the brightest objects in the sky, Hwahye-yyang has been a major inspiration in native folklore for as long as records have existed.
The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 18 meters.
Surrounding Hwahye-yyang is a irregular planetary ring system and a powerful magnetosphere. |
