When Voyager 2 was routed to fly by Saturn, it was originally the plan to have the satellite fly through the Cassini gap. Why would this have been a bad idea?
A) That route would have taken Voyager 2 within the Roche Limit and the satellite would have been torn to pieces. B) That route would have taken Voyager 2 inside Saturn's magnetic field causing the electronics on board to be destroyed. C) The Cassini gap actually contains a large moon that orbits Saturn with a very high speed and Voyager 2 would have collided with that moon. D) The gaps in Saturn's ring system (including the Cassini gap) are not actually empty space, rather they are an area of low density in the rings. E) Voyager 2 would have encountered density waves which would have crushed the satellite.
