Today in History: Lexel's Comet Almost Hits Earth

On this day (July 1) in 1770, Lexel’s Comet came closer to the earth than any other recorded comet. It passed a mere 1,400,000 miles from our planet. Lexel’s Comet has not been seen since, and is considered lost. But obviously what came close once could come close again sometime in the future… Now there’s a good story idea! But, of course, it’s already been done many times. Anyone remember Lucifer’s Hammer?
