| Suggested name | Elwen |
| Planet type | Hot gas giant |
| This planet is named after the deity Elwen, the bringer of love and beauty.
As the closest planet to Ouywang Nei, Elwen has been a prime target for early extra solar exploration. Elwen's hazy clouds make observation of its surface impossible in infrared light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 52 years ago.
The rotational period and seasonal cycles of Elwen are likewise similar to those of Earth, as is the tilt that produces the seasons.
Because of its fast rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator).
Elwen has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Galileo orbiter. |
