Fictional info (?) 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 named after the deity Baba Yaa, the god of good fortune. It is radically different from Earth in other respects. The atmospheric pressure at the planet's surface is 0.001 bar, or roughly the pressure found 585 m under the oceans of Kinyobu. Baba Yaa is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. 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. Plans have been proposed for rovers or more complex missions, but they are hindered by Baba Yaa's hazardous precipitation. Surrounding Baba Yaa is a irregular planetary ring system and a powerful magnetosphere. Baba Yaa has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Hotchins orbiter.
