Fictional info (?) |
Suggested name | Oujaixyuany |
Planet type | Huge cold gas giant |
It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets. Orbiting within Yingqwei's orbit, Oujaixyuany is an inferior planet and never appears to venture far from KMT-2019-BLG-0842; its maximum angular distance from KMT-2019-BLG-0842 (elongation) is 77 degrees.
This huge cold gas giant is named after the deity Oujaixyuany, the demon of the underworld.
Like Yingqwei, Oujaixyuany has been orbiting KMT-2019-BLG-0842 within Zheih-en's orbit as an inferior planet, and never moves more than 15 degrees away from KMT-2019-BLG-0842.
Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator).
The Oujaixyuany system has a unique configuration among those of the planets because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. In 1589, images from Wayfinder 4 showed Oujaixyuany as an almost featureless planet in visible light, without the cloud bands or storms associated with the other huge cold gas giants. |
