A friend showed me an article saying that there's evidence that a piece of Halley's comet may have struck the earth about 1,500 years ago. Is anyone here aware of such evidence?

The talk at AGU was last Wednesday, guess we'll have to wait for the proceedings. Seems to be pretty new. blogs.ei.columbia.edu/2013/12/06/… – Alexander Janssen Dec 19 '13 at 21:10

I have not read the complete scientific article, but I'm not prone to trust this. On that year the Chinese civilization were quite well established and annotating about comets, and I have not read about them annotating about a comet that approached so much to Earth.

The Chinese might not have seen the impact if it was on the other side of the world, or over an ocean. But I'm inclined to agree with you over all. Is it possible the Earth was hit by a comet around 530 AD - sure. Was it a piece of Halley's comet? Er . . . I'm skeptical too. – userLTK Jul 16 '15 at 18:29
