Suggested nameRyogyo Pucha
Planet typeCold planet
Ryogyo Pucha has been known to astronomers since antiquity. It is named after the deity Ryogyo Pucha, the god of nature.

When viewed from Earth, this proximity to HD 155193 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.

It has the densest atmosphere of the two cold planets, consisting partly of hydrogen deuteride (HD). Ryogyo Pucha is by far the hottest planet in its solar system, with a mean surface temperature of 674°K (401°C).

In 1390, images from Daedalus 6 showed Ryogyo Pucha as an almost featureless planet in visible light, without the cloud bands or storms associated with the other cold planets.
