Xephisiss-231 refers only to one comet (shooting star). It never exists. That is just a name I came up with. It is not a scientifically correct naming since numbers (231) and letters (alpha, betta, gama, etc) normally are used in the context of a group of cosmetic objects like constellation or remote star- planet systems.
