Near Miss Day – March 23, 2025

Near Miss Day is celebrated on March 23, each year. What would you do if a huge asteroid was about to hit planet Earth? On March 23, 1989, an asteroid about the size of a mountain came very close to colliding with the Earth. Thankfully, it was a near miss! Otherwise, the effect of the collision would have been devastating. People around the world celebrate this day to be grateful that the asteroid didn’t wipe us out! According to scientists and astronomers, many meteoroids and asteroids have passed by the Earth since 1989. However, the odds of an asteroid hitting the Earth are not high. That’s a relief!

History of Near Miss Day

Ever wondered what an asteroid is? Asteroids are rocks that were formed after the formation of our solar system — they are the leftovers of a great process. Asclepius is an asteroid with a diameter of 0.431 kilometers, comparable to the size of a football field. 

On March 22, 1989, Asclepius passed by the Earth at a distance of almost 500,000 miles. However, scientists only discovered this after nine days. Many geophysicists believe that the collision of Asclepius with the Earth would have wreaked havoc, resulting in the release of energy comparable to a 600 megaton atomic bomb! 

The reason this day has great importance is that the Earth nearly escaped from an apocalypse. We all got a second chance at life. This event changed our perspective on cosmic influences — it made us realize that humankind has absolutely no control over the universe. 

Since that day, there have been advanced changes in space programs. Missions were organized and space shuttles were sent to nearby planets to study life on them. Near Miss Day also reminds us that asteroids and meteors can lead to the extinction of the Earth and the human race.
