Fictional info (?)
Suggested nameMoonpoan Hege
Planet typeCold gas giant
Moonpoan Hege 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. Moonpoan Hege is orbiting KMT-2017-BLG-1146 every @ORBITALPERIOD Earth days.

For this reason, scientists often classify Moonpoan Hege and Kinsiemona as "cold gas giants" to distinguish them from the other planets. It is named after the deity Moonpoan Hege, the creator of destruction.

The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to KMT-2017-BLG-1146, which reoccurs over the so-called synodic period approximately every 128 days.

Optical ground-based telescopes are typically limited to resolving features about 465 kilometers across when Moonpoan Hege is closest because of Kinsiemona's atmosphere.
