When X-Factor was transported to a distant unknown world by X-Factor's Ship they encountered the Celestials for the first time. In orbit of the world was a ship larger than a moon. It remained in orbit, while the Fifth Celestial Host judged the world below. At least 50 Celestials were on that ship.
Once the world was spared due to the actions of X-Factor, the Celestial ship launched a monitoring vessel (similar in shape and size to the Manhattan island-sized X-Factor's Ship) which would continue to monitor developments on that world just as X-Factor's Ship did for millennia on Earth.
