Caim: Kepler-155c

Relatively speaking, Kepler-155c has gotten little attention. In the habitable zone with a 52 day year, it orbits an orange dwarf, and can be considered a super-Earth since it’s nearly two and half times larger than our planet. 


Yet it might be more useful to think of this exoplanet as a ‘hot Neptune.’ There is no information on the mass of 155c, but given its size I doubt it’s rocky. This leads me to suspect that it may be a gaseous planet or ‘gas dwarf’ (as opposed to a ‘gas giant’), which is usually a planet that’s at this kind of nearness to its star with a radius between 1.7-3.9 Earth-radii. 


I wouldn’t write this exoplanet off as a possibility for otherly life. Gas planets, whether dwarf or giant, I suspect have in their orbit a plethora of moons analogous to our own solar system. Those moons may very well be the kind of thing we’re into.


It’s pushing it to place Kepler-155c into the category of gas dwarf or hot Neptune. From what little, very little, we know of the world, it’s nothing more than a super-Earth. I like to imagine that this world has a gaseous atmosphere but a rocky core that is Earth-like. Perhaps this planet has a layer that obscures it or coats it making the surface something quite unique. It’s atmosphere as a sort of caim circle, which leads me to the name:


A caim (pronounced ‘kyem’) is kind of ring of protection or protecting spirit. It’s also just as frequently cited as the Celtic version of the name ‘Cain.’ I think the ambiguity works well and gives some spice to this quite exoplanet.
