A massive asteroid (4581 Asclepius) nearly hit the earth in 1989. This day is commemorated annually on March 23 as people across the nation celebrate National Near Miss Day.
On March 22-23, 1989, a mountain-sized asteroid came within 500,000 miles of colliding with the earth. “On the cosmic scale of things, that was a close call,” said Dr. Henry Holt. Geophysicists estimate that collision with Asclepius would release energy comparable to the explosion of a 600 megaton atomic bomb. On March 31, 1989, nine days after its closest approach to Earth, the asteroid was discovered.
A collision would have had catastrophic effects on our planet.
There have been other “near misses” that have happened on an infrequent basis.
