afree87 writes: "A re-analysis of historical observations at a Mexican observatory suggests Earth narrowly avoided an extinction event just over a hundred years ago. On 12th and 13th August 1883, an astronomer at a small observatory in Zacatecas in Mexico made an extraordinary observation.

"If they had collided with Earth we would have had 3275 Tunguska events in two days, probably an extinction event.""
