Of course, i know it could be considered morbid and while this is not exactly something likely... Damn what a sight to see if you could get in space out of the way of the blast. You would be witnessing a cosmological event that may, or may not ever be witnessed again but, you'd probably never be able to share the tale... It would be a scene unimaginable to actually meet the eyes. The study of the event like that (on a planet not ours) would be fascinating if we could observe it remotely. While a rogue planet wouldn't throw the whole solar system into disarray automatically, like I said before, if it was on a collision course with our planet and just two days away we'd know it.
