Fictional info (?)
Suggested nameBertepho Pa
Planet typeWarm planet
It is named after the deity Bertepho Pa, the creator of love and beauty.

An observer on Bertepho Pa 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, Bertepho Pa's distance from Proxima Centauri is only about two-thirds (or 36 pct) of its distance at aphelion. Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 60°K (-213°C) at night to 840°K (567°C) during the day across the equatorial regions.

Bertepho Pa can easily be seen from Ronmona Ymir with the naked eye, as can its grayish coloring.

The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. A prominent result is the "great white spot", a giant storm that is known to have existed for centuries since it was first observed by radar.
