| Suggested name | Halilyke |
| Planet type | Cold planet |
| It is a cold planet planet with a mass one-thousandth that of GJ 752 A, but two-and-a-half times that of all the other planets in its solar system combined.
Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 125°K (-148°C) at night to 1155°K (882°C) during the day across the equatorial regions.
It has the densest atmosphere of the cold planets, consisting mostly of 2H2O. |
| Atmosphere | 2H2O | 79% |
| Ammonia | 17% |
| Hydrogen peroxide | 3.5% |
| Hydrogen deuteride (HD) | 0.021% |
| Molecular hydrogen | 1.5E-5% |
| Atmospheric pressure | 0.001 bar |
