Considering that the closest star to Earth is a little over 4 light years away, and there are 8 stars within 10 light years, if ISON were interstellar, it would only make sense that it came from one of our closest neighbors.
Quoting: hatch battener 50098992 If ISON were interstellar, it would have an eccentricity much greater than 1. Most of these stars are traveling relative to us at many km/sec, and any of their comets would not be traveling very fast at all relative to their parent stars in order for them to remain gravitationally bound within their Oort clouds. Such a comet would, however, be traveling well above escape velocity relative to our sun. It would be strongly hyperbolic (1.1 at least), but instead it is only narrowly hyperbolic. From Astro's own figures, ISON might not just be a good show from our region of space, but may be seeding interstellar elements into our solar system, until all civilization is destroyed!
Quoting: hatchActually it seems that it will seed OUR elements into interstellar space. Perhaps that's the real doom. Poor universe will never see it coming. Uh-oh. The whole of the universe will end up like O'Hare - Thread: Stuck at Chicago O'Hare for 8 Hours. Ask me a question.
