Fictional info (?)
Suggested nameHangs-wang
Planet typeHot planet
In English, Hangs-wang is often referred to as the "blue planet" because the xenon prevalent on its surface gives it a strange blue appearance that is unusual among the astronomical bodies visible to the naked eye.

This planet is named after the deity Hangs-wang, the spirit of chaos.

Two spacecraft have visited Hangs-wang: Daedalus 10 flew by 53 years ago; and Messenger, launched 20 years ago, orbited Hangs-wang over 175 times in four years before exhausting its fuel and crashing into the planet's surface 5 years later.

It has the densest atmosphere of the known hot planets, consisting mostly of oxygen.

There are ongoing investigations assessing the future terraforming potential of Hangs-wang, as well as the possibility of extant life.

Optical ground-based telescopes are typically limited to resolving features about 300 kilometers across when Hangs-wang is closest because of Yetyang-lyue's atmosphere.

It may also have a rocky core of heavier elements, but like the other hot planets, Hangs-wang lacks a well-defined ozone layer.
