| Suggested name | Yaolyeq-ya |
| Planet type | Huge cold gas giant |
| It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 40°K (-233°C), and has a complex, layered cloud structure with nitric oxide thought to make up the lowest clouds, and hydrogen deuteride (HD) the uppermost layer of clouds.
As seen relative to the fixed stars, it rotates on its axis exactly four times for every two revolutions it makes around 2MASS J0441+2301 A.
It may have had krypton oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). |
| Atmosphere | Hydrogen deuteride (HD) | 50% |
| Nitric oxide | 43% |
| Krypton | 5.8% |
| Methane | 0.00037% |
| Atmospheric pressure | 0.5 bar |
