National Near Miss Day

National Near Miss Day is a holiday that’s observed on March 23rd to commemorate a very scary event that happened at the end of the 1980s. On March 23, 1989, an asteroid nearly struck the Earth, but fortunately flew right on by.

This was asteroid 4581 Asclepius and it was the size of a football field and came within half a million miles of making contact with our planet. That might not seem like a close call to most people, but on a planetary scale, it was indeed a very close call. If the asteroid would’ve made contact with the Earth, then things would’ve been pretty bad.
