| Suggested name | Urehe-ryjax |
| Planet type | Cold planet |
| Its orbital period around Kepler-557 of 3.7 earth days is the shortest of all the planets in its solar system.
The nitrogen has probably photodissociated, and the free methane has been swept into interplanetary space by the solar wind because of the lack of a hydrogen peroxide layer. |
| Atmosphere | Methane | 51% |
| Krypton | 18% |
| Nitrogen | 12% |
| Hydrogen peroxide | 7.5% |
| 2H2O | 4.7% |
| Carbonyl sulfide | 4.4% |
| Ammonia | 1.5% |
| Atmospheric pressure | 0.006 bar |
