Since mass loss would seem slight, might a comet’s orbit have originated billion of years ago? Perhaps destabilized from early Oort cloud formation, by an ejected gas giant? So might a collisional effect for Uranus, long period comet orbit formation, and any gas giant ejection from our system, have a relationship? Would such gas giant planet be detectable in infrared, and distinguishable from a sister star red dwarf?

How old are cometary orbits? Ejected gas giant etiology?
