What is Near Miss Day?
Near Miss Day is observed annually on March 23rd to commemorate the day in 1989 when a massive asteroid narrowly missed colliding with Earth. The asteroid, known as 4581 Asclepius (1989 FC), came within approximately 700,000 kilometers (about 435,000 miles) of our planet. If it had impacted, the asteroid, which is about the size of a mountain, could have caused significant devastation. Near Miss Day serves as a reminder of the importance of monitoring near-Earth objects (NEOs) and investing in planetary defense strategies to detect and potentially deflect objects that pose a threat to Earth.
History and Origin
The event that led to the establishment of Near Miss Day occurred on March 23, 1989, when asteroid 4581 Asclepius passed extremely close to Earth. The asteroid’s near miss was not detected until after it had already passed, highlighting the need for better surveillance of space objects that could pose a danger to our planet. Since then, efforts to track NEOs have increased, with organizations like NASA’s Planetary Defense Coordination Office and various international agencies working to identify and monitor potential threats from space.
