I don’t quite agree with the size estimate or the idea that it is a ‘solid’ mass. It could be a sort of TRUE Dyson Sphere, possibly made of gas enclosed within a stable electrical or magnetic field. That matches with Purple Dawn Theory where gas giants such as Jupiter and Saturn are sheaths that contain terrestrial planets with them. (Dyson Sphere wiki)
Regardless, this is a beautifully created video.
From the YT description: I have added this video as it shows from multiple satellites and multiple wavelengths the scale of these Titanic objects that have been here since 2007.
