Fictional info (?)
Suggested nameHehyage-ku
Planet typeCold planet
For this reason, scientists often classify Hehyage-ku and Unufu Bu as "cold planets" to distinguish them from the other planets. It is named after the deity Hehyage-ku, the bringer of fear.

It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.

In late February 2900, Hehyage-ku was visited by the New Horizons probe, which used Hehyage-ku's gravity to increase its speed and bend its trajectory en route to Unufu Bu.
