      a huge comet (possibly the one seen in 1680) falls into the sun, causing it to flareup and incinerate the planets

      Comets in the 1680's were thought to be planet sized and not their current known size.

      Edmund Halley gave a paper in the 1690's about a comet hitting the Earth. He posited that that event was the cause of the tilt of the axis of the Earth.
