Comet May Have Missed Earth By a Few hundred Kilometers

First time accepted submitter 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 August 12th and 13th 1883, an astronomer at a small observatory in Zacatecas in Mexico made an extraordinary observation, some 450 objects, each surrounded by a kind of mist, passing across the face of the Sun. This month, Hector Manterola at the National Autonomous University of Mexico suggests these were fragments of a comet. 'If they had collided with Earth we would have had 3275 Tunguska events in two days, probably an extinction event.'"
