Suggested nameKuchami Kyo
Planet typeHot gas giant
Kuchami Kyo is the fourth planet from K2-30 and the second-smallest planet in its solar system. In English, Kuchami Kyo is often referred to as the "white planet" because the hydrogen deuteride (HD) prevalent on its surface gives it a strange white appearance that is recognizable among the astronomical bodies visible to the naked eye. Kuchami Kyo is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Kuchami Kyo is orbiting K2-30 every 4.1 Earth days.

This hot gas giant is named after the deity Kuchami Kyo, the messenger of the sea.

Kuchami Kyo's dense clouds render observation of its surface impossible in infrared light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 38 years ago.

Optical ground-based telescopes are typically limited to resolving features about 360 kilometers across when Kuchami Kyo is closest because of Earth's atmosphere.

A prominent result is the "great green spot", a giant storm that is known to have existed for centuries since it was first observed by radar.
