The sheer sight of that simulated model makes me wonder if you're being sarcastic, but the story doesn't say whether it's a simulation or just made up.
He's joking. We don't have satellites the size of entire cities. If this were to scale, it would look exactly like the pictures of earth we are used to seeing with nothing but black surrounding it.
There's a lot of space debris, but there's a whole heck of a lot more "space."
