Reading this speculation about a cometary near-miss 128 years ago (via Instapundit), one breathes a sigh of relief while reflecting on how no planetary defensive measure would have much chance of staving off “3275 Tunguska events in two days”.
But then I thought, “Hold on. Wouldn’t a comet with 3,000 Tunguska-sized fragments be surrounded by billions of lesser particles? If it passed within 500 miles of the Earth, wouldn’t the meteor shower be remembered to this day?”
So I asked Dr. Bing about “meteor showers 1883” and promptly learned that, far beneath an alarmist headline – “Revealed: The massive comet that came within a few hundred miles of hitting the earth in 1883 - with enough force to destroy mankind” – even the scarcely reliable Daily Mail had noted,
The report’s claims have been questioned, though, as a comet breaking up so close to earth should have resulted in a meteor shower, and no astronomers detected one.
The regular Perseid meteor shower, which occurred shortly after Bonilla’s photograph, was described in reports as ‘not a fine one by any means.’
It was, admittedly, a spectacular year for the Leonid shower:
One of the most memorable Leonid meteor showers reported was the one that occurred in 1883. It was superlative in intensity that an estimated 100,000–200,000 meteors an hour were seen over North America. People who have observed it from the best locations actually thought that the world is ending. The 1883 event led to the first formulation of the origins of meteors.
But the Leonids are in November, three months after the supposed multi-Tunguska, and have been observed for centuries.
So the world didn’t almost end in August 1883, but, hey, maybe that was a fleet of alien starships cruising by.
