| Suggested name | Menere |
| Planet type | Large hot gas giant |
| Its orbital period around HATS-36 of 4.2 earth days is the shortest of all the planets in its solar system. It is the second-brightest natural object in the night sky after Corme, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.
Menere and Corme are large hot gas giants rich in ice. Menere's atmosphere is similar to Corme's in its primary composition of oxygen and formaldehyde, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. 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 formaldehyde thought to make up the lowest clouds, and oxygen the uppermost layer of clouds. It is named after the deity Menere, the spirit of prosperity.
The ozone has probably photodissociated, and the free oxygen has been swept into interplanetary space by the solar wind because of the lack of a water vapor layer.
Plans have been proposed for rovers or more complex missions, but they are hindered by Menere's hazardous precipitation.
There are ongoing investigations assessing the present habitability potential of Menere, as well as the possibility of extant life. |
