| Suggested name | Yomyo |
| Planet type | Cold planet |
| When viewed from Kugyobu Jo, Yomyo can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. This cold planet is named after the deity Yomyo, the spirit of war.
At this time it may appear as a bright star-like object, but is often far more difficult to observe than Kugyobu Jo.
Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Yomyo's distance from Kepler-628 is only about two-thirds (or 46 pct) of its distance at aphelion.
Yomyo is by far the hottest planet in its solar system, with a mean surface temperature of 761°K (488°C).
The smooth Borealis basin in the northern hemisphere covers 30 percent of the planet and may be a giant impact feature.
Future astrobiology missions are planned, including the Yomyo 3200 and ExoYomyo rovers. |
