Fictional info (?) |
Suggested name | Gwang-nyang |
Planet type | Hot planet |
The planet is named after the deity Gwang-nyang, the god of hate.
Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Gwang-nyang's distance from LHS 1678 is only about two-thirds (or 53 pct) of its distance at aphelion.
The rotational period and seasonal cycles of Gwang-nyang are likewise similar to those of Wazhai, as is the tilt that produces the seasons.
Future astrobiology missions are planned, including the Gwang-nyang 1700 and ExoGwang-nyang rovers. Liquid water cannot exist on the surface of Gwang-nyang due to low atmospheric pressure, which is less than 9 percent of Wazhai's, except at the lowest elevations for limited periods. |
