| Suggested name | Drapa |
| Planet type | Hot planet |
| Drapa has been known to astronomers since the beginning of the space age. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 58°K (-215°C), and has a complex, layered cloud structure with methane thought to make up the lowest clouds, and carbon monoxide the uppermost layer of clouds. It is named after the deity Drapa, the messenger of hate.
Liquid water cannot exist on the surface of Drapa due to low atmospheric pressure, which is less than 3 percent of Earth's, except at the lowest elevations for short periods.
Its apparent magnitude reaches -3, which is surpassed only by Pephaë, Hergetur Gel, and GJ 581. |
