| Suggested name | Shuhyo |
| Planet type | Cold planet |
| This cold planet is named after the deity Shuhyo, the demon of prosperity.
An observer on Shuhyo would therefore see only one winter every five years.
Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Shuhyo's distance from GJ 752 A is only about two-thirds (or 109 pct) of its distance at aphelion.
Shuhyo is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
As the closest planet to Bemyushi, Shuhyo has been a prime target for early interplanetary exploration.
Future targets for exploration in the Shuhyo system include the probable ice-covered liquid ocean of its moon Pusahe-pyoji Fu. |
