Fictional info (?)
Suggested nameYangtyuan-t
Planet typeTerrestrial
This planet is named after the deity Yangtyuan-t, the creator of war.

Like Yunwan Palyang, Yangtyuan-t has been orbiting HD 221416 for 4.9 billion years, and never moves more than 32 degrees away from HD 221416.

There are ongoing investigations assessing the present habitability potential of Yangtyuan-t, as well as the possibility of extant life. Future astrobiology missions are planned, including the Yangtyuan-t 3100 and ExoYangtyuan-t rovers.
