Fictional info (?)
Suggested nameByapyuya-ju
Planet typeTerrestrial
Byapyuya-ju is the strangest and most well-known planet in its solar system.

This planet is named after the deity Byapyuya-ju, the god of destruction.

An observer on Byapyuya-ju would therefore see only one sunrise every two years.

Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Byapyuya-ju's distance from 55 Cnc is only about two-thirds (or 116 pct) of its distance at aphelion. The polar regions are constantly below 171°K (-102°C).

Surrounding Byapyuya-ju is a large planetary ring system and a powerful magnetosphere.

In 2880, images from Daedalus 4 showed Byapyuya-ju as an almost featureless planet in visible light, without the cloud bands or storms associated with the other terrestrials.
