Well, even if something is massive in orbit, if you get any farther than 2 kilometers away from it, it disappears from view. Sorry about that. Before 0.13 (I think) you could see stuff pass over you like Tosh\'s Jupiter or GoDammit\'s death star. But, a benefit from that is that it let\'s KSP process information much faster, so that way the game doesn\'t slow to a crawl.
