A hypothetical view of the surface of HD 219134 c, the second planet of the HD 219134 system. The system probably has 7 planets, all uninhabitable. The star HD 219134 itself is a sun-like main sequence star at a distance of 21 light years, somewhat smaller, fainter and lower in mass than the sun.
HD 219134 c is a rocky super-Earth with more than 4 times the mass and 1.5 times the diameter of the Earth. Its gravity is twice that of the Earth and its surface temperature is over 500° C. It is so hot that there are puddles of molten metals with a low melting point, such as lead, etc. HD 219134 c revolves very close to its sun, so it has a locked rotation: One side always has day, the other always night.
If the planet has an atmosphere, it probably consists of various volcanic gases under tremendous pressure, more a very stormy dense gas envelope than a layered atmosphere.
It is probably a huge, second Venus, only even more inhospitable. However, it is probably much brighter than on Venus. Due to its proximity, HD 219134 c receives 50-60 times more light and energy from its parent star than the Earth receives from the sun.
