About Near Miss Day

When is Near Miss Day? This holiday is always celebrated on March 23

Near Miss Day commemorates the day a huge Asteroid nearly missed hitting the earth.

On March 23, 1989, an asteroid the size of a mountain, came within 500,000 miles of a collision with Earth. In interstellar terms, it was a near miss. Had it collided with the Earth, it would have left a devastating crater the size of Washington, D.C. It’s affect on the planet would have been catastrophic. Since then, there have been other near misses.


 Near misses with large, potentially life threatening galactic objects happens on an infrequent basis.  It is believed a large asteroid collided with the earth and caused the extinction of dinosaurs. Scientists believe it is only a matter of time before another catastrophic collision with Earth. But, don’t worry. The odds are it will not happen for a long, long time.   

Asteroids Versus Meteors

The terms Asteroid, Meteor, and Meteorite are often confusing. Here are the definitions:

Asteroids are objects in space that orbit the sun. They are of any size in space. They are sometimes called “space rocks”. It’s the big ones that we worry may potentially hit the earth and cause catastrophic damage.

Meteors are asteroids that enter the earth’s atmosphere. Most meteors burn up in the earth’s atmosphere, putting on a light display as they streak across the sky.

Meteorites are small meteors, sometimes as small as a grain of sand. A meteor that survives the atmosphere to hit the earth’s surface is called a meteorite.

Comets – consist mostly of ice and dust. It orbits the sun or comes from the outer reaches of the solar system. They develop a tail as they near the sun and the sun heats them up.

History and Origin of Near Miss Day

Our research did not find the creator or the origin of this day.

A few internet sites are referring to this holiday as National Near Miss Day. An Asteroid hitting the earth would likely have worldwide implications, making this a candidate for an international holiday rather than a national one. We found no documentation in congressional records to confirm that this is truly a national day. Nor, did we find a presidential proclamation.
