It fell at 50,000 kilometers per hour, plowing through the North Carolina sky: its scorching trail was visible from an altitude of 60 kilometers to 35, a journey during which the meteor shattered the sound wall causing a thunderous roar in the evening. Then the explosion that crumbled the fireball on the vertical of the city of Morehead. A magnificent sight.
And to say that according to the American Meteor Society (Ams) in those hours there were 5 clearly visible meteorites that impacted the atmosphere. The Meteor Watch association of NASA has released the video of the fireball, the last of the more than 600 recorded this year, some so evident that they have been identified in multiple countries.
Again according to NASA, about fifty tons of alien material are within range of the atmosphere every day. Very little material (5%, approximately 250 kilograms) that does not completely incinerate when crossing it, even less the surviving material that does not disappear in the waters that cover two thirds of the globe. And even fewer those that can be recovered, perhaps identifying them for their “burned” appearance.
Dangers for the Earth and for the terrestrials? NASA calculates a possibility every 10,000 years regarding “devastating impact” by Near Earth Objects (objects close to the Earth): just under a thousand are cataloged.
