So I just saw TFA and was just wondering this about starkiller. How did it maintain orbit after destroying its Sun? I don't think that destroying a planets sun would be very good for it.

  • Yeah I know there are rogue planets..But it doesn't make sense for such an important and expensive battle station to be floating around freely in space, and possibly getting destroyed by a collision with some other planet. – mayank budhwani Dec 28 '15 at 12:58
  • Even drained of its energy, the remnants of a star would still have mass, causing gravity, and keep things in orbit. – phantom42 Dec 28 '15 at 12:59
  • @phantom42 - the novelization very explicitly states that the system Starkiller was in became a binary after Starkiller Base went nova – DVK-on-Ahch-To Dec 28 '15 at 16:08
