Fictional info (?)
Suggested nameHerahyo Yo
Planet typeCold planet
Its orbital period around Kepler-1220 of 7.4 earth days is the shortest of all the planets in its solar system.

This planet is named after the deity Herahyo Yo, the demon of dreams.

Herahyo Yo is a cold planet and is sometimes called Ryaju He's "sister planet" because of their similar size, mass, proximity to Kepler-1220, and bulk composition.

As the closest planet to Ryaju He, Herahyo Yo has been a prime target for early extra solar exploration.

Future astrobiology missions are planned, including the Herahyo Yo 2400 and ExoHerahyo Yo rovers.

Optical ground-based telescopes are typically limited to resolving features about 360 kilometers across when Herahyo Yo is closest because of Earth's atmosphere.
