257 Foot Diameter Asteroid Passing Near Earth
The first time the asteroid ‘(2015 MX103)’ was detected was on Jun 19, 2015. Since 1966 it has passed Earth 12 times.
(2015 MX103) is 115 foot to 257 foot in diameter and will pass by Earth at a distance of 30,515,752 miles.
Fun Fact: If this asteroid was a member of a frequent flyer club, it would amass 786,158 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.
