| Suggested name | Yonyue |
| Planet type | Small cold gas planet |
| As seen from HD 22946, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
Because of its fast rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). |
