| Suggested name | Qisi Tar |
| Planet type | Cold planet |
| It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 53°K (-220°C), and has a complex, layered cloud structure with ammonium hydrosulfide (NH4SH) thought to make up the lowest clouds, and hydrogen the uppermost layer of clouds.
As seen from HIP 8541 A, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
The volume of water detected has been estimated to be equivalent to the volume of water in the Black Sea. |
| Atmosphere | Hydrogen | 91% |
