First-Ever Halley Comet Sighting: It Was All Greek

I caught this from the newsfeed at the bottom of the blog.

..........the mention of a comet falling somewhere in the Hellespont region of northern Greece, either in 466 or 467 BC. Hintz and Graham write that records from the time describe how the meteor fell even while a continued to burn in the sky. (It subsequently became a tourist attraction for the next 500 years.) However, most of the subsequent commentary focused on the meteor, giving the appearance of the comet relatively short shrift.

Fast forward to 1705. That's when Englishman Edmond Halley correctly predicted the return of a comet seen in 1682, which returned to pass by the Earth in 1758. Since then, scientists have been able to project backwards the comet's return trips, which typically take place every 75 to 76 years.

Using computer simulations Hintz and Graham suggest that what we now call Halley's comet might have been visible for about 80 days during the summer of 466 BC.
