| Suggested name | Baba Yaa |
| Planet type | Small cold gas planet |
| 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 sulfur dioxide thought to make up the lowest clouds, and ammonium hydrosulfide (NH4SH) the uppermost layer of clouds.
It is radically different from Earth in other respects. The methane has probably photodissociated, and the free ammonium hydrosulfide (NH4SH) has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field. |
