| Suggested name | Atmaka'dilno |
| Planet type | Hot gas giant |
| It is a hot gas giant planet with a mass one-thousandth that of HAT-P-57 A, 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 2H2O thought to make up the lowest clouds, and oxygen the uppermost layer of clouds. When viewed from Earth, this proximity to HAT-P-57 A means the planet can only be seen near the western or eastern horizon during the early evening or early morning. |
