[THIS IS A SAMPLE ARTICLE FROM OUR ARCHIVES]
Today the large asteroid ‘523605 (2004 RX10)’ is zipping past Earth, thankfully missing by 35,273,988 miles.
The first time the asteroid ‘523605 (2004 RX10)’ was observed was on Sep 08, 2004. Since 1900 it has passed Earth 178 times and we can expect it to return two hundred and seventy-eight more times within the next 100 years.
523605 (2004 RX10) is 479 foot to 1,072 foot in diameter and is passing by Earth at a distance of 35,273,988 miles.
Fun Fact: If this asteroid was a member of a frequent flyer club, it would amass 758,875 frequent flier miles per day.
Tracking asteroids and comets was a lot harder until 2016 when NASA opened the Planetary Defense Coordination OFfice (PDCO), which formalized the process of detecting near-Earth Objects (NEOs).
When small pieces of debris or chuncks of asteroids or comets enters the earth atmosphere, they become meteors which in turns sometimes become fireballs. A more romantic name for meteors is of course shooting stars. The pieces that do not burn up upon entry can be very valuable to collectors if they can be found after they hit the ground.
Just this year NASA discovered a giant 22-mile wide crater buried under the Greenland Ice Cap. The crater, if confirmed, could turn out to be one of the largest known impacts an asteroid has had with Earth.
