| Suggested name | Hebo'suwa-e |
| Planet type | Large cold gas giant |
| It is a large cold gas giant planet with a mass one-thousandth that of GALEX 0718+3731, but two-and-a-half times that of all the other planets in its solar system combined. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 85°K (-188°C), and has a complex, layered cloud structure with hydrogen chloride thought to make up the lowest clouds, and sulfur dioxide the uppermost layer of clouds. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to GALEX 0718+3731, which reoccurs over the so-called synodic period approximately every 139 days.
