We've run into this problem before, to my knowledge the scale of both the GSR and Spherus Magna had been scaled down, first I think the projected size of Spherus Magna was about 10 or maybe even 100 times larger than Jupiter, I don't exactly recall which, but it was gargantuanly absurdly large for ANY terrestrial (meaning rocky) planet, even when compared to more so recent Exoplanet discoveries, I believe one of the largest ones found was around the size of Jupiter, but to my understanding, just getting to that diameter is pretty much the physical scientific limit for rocky worlds to get to, gas planets are of course different, but that's regardless. Than I believe both the GSR and Spherus Magna were scaled down, Spherus Magna down to about the size of Jupiter, and the GSR to about the size of Pluto, which is about the same area of land as the whole of Russia. Now, on a slightly different note, within a project I am a part of, which is a continuation project, I and the main head of the project through our own independant work came to about the same more rational conclusions for the scale of both the GSR and Spherus Magna, my measurement for Spherus Magna came out to be 1.42 or so Earth Masses, which makes it a bit larger than the earth as well as a bit wider, and the GSR around the size of the Canadian territory of Nunavut. It makes it that the GSR is reasonably sized, and Spherus Magna too is reasonably sized. The whole notion of the GSR not being viewable from space, and that Spherus Magna is ten or more times the size of Jupiter is utterly absurd and scientifically and physically impossible, it's just too big.
