K.yuk'o (Kai'pua IV)

K.yuk'o (Kai'pua IV) is the fourth planet from the sun of the Kai'pua system, Xi'an Empire (SaoXy'an), and is a gas dwarf. Since its rocky core and diffuse atmosphere have nearly identical properties to those of neighboring planet Kyu'kyu (Kai'pua III), some astronomers speculate that they may have originally formed in the same region before drifting away from each other. One hypothesis suggests that a rogue planet sliced through the system and pulled K.yuk'o out of its original orbit.
