Suggested nameRyori Rya
Planet typeHuge cold gas giant
Its orbital period around HIP 21152 of 22000 earth days is the shortest of all the planets in its solar system. It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.

This huge cold gas giant is named after the deity Ryori Rya, the spirit of destruction.

As seen relative to the fixed stars, it rotates on its axis exactly three times for every four revolutions it makes around HIP 21152.

Ryori Rya's surface is a dry desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.

Its apparent magnitude reaches -3, which is surpassed only by Pyoshi Binu, Myobya, and HIP 21152.

The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.

The largest moon is dangerous because of the odd and stone-age insects known to feed in deep valleys by hunting something called Motasenya. Most of them are closely related to the Ronge-byo but have 2 legs and vary in size from 6 to 8 mm. They are able to endure temperatures from 130 to 240°C and even near-vacuum.
