141 Foot Diameter Asteroid Passing Near Earth
The first time asteroid ‘(2014 GG49)’ was observed was on Apr 09, 2014. Since 1996 it has passed Earth 16 times and within the next 100 years it will return 6 more times, getting as close as 5,491,879 miles to Earth in 2087.
(2014 GG49) is 63 foot to 141 foot in diameter and is passing by Earth at a distance of 12,520,283 miles.
Fun Fact: If this asteroid was a member of a frequent flyer club, it would amass 810,629 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.
