| Suggested name | Lypmab |
| Planet type | Small cold gas planet |
| It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
As seen from Kepler-289, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
The hydrogen has probably photodissociated, and the free ozone has been swept into interplanetary space by the solar wind because of the lack of a ammonia layer. |
