A meteorite that survived atmospheric access and struck the roof of a house in Georgia earlier this year may have formed before the earth itself, according to a scientist from the University of Georgia who analyzed fragments of the roaming solar system object.
Inhabitants of different Southeast -American states were blinded on July 26 when they witnessed one Rare fire ball during the day – Clear enough to be registered by a satellite in a job – blazing on the earth.
The old asteroid shard in the heart of the event has passed the intense friction of atmospheric access to hit a hole through the roof of a house in the city of McDonough, Georgia, smashed the floor just 14 feet (4 meters) from a non -positive resident.
How old is the McDonough Meteorite?
23-gram value of the fragmented meteorite-the name given to meteoroids who later reached intact-warden to the University of Georgia (UGA), where scientists were at work to unravel the secrets of the origin. “This specific meteor that entered the atmosphere has a long history before it has achieved the ground of McDonough, and to fully understand that, we must actually investigate what the rock is and determine which group of asteroids it belongs,” ” said UGA researcher Scott Harris.
The newly mentioned McDonough Meteorite is considered a normal chondrite with a layer of metal (L) – one of the The most old forms of rock known to exist in the solar system – That was probably about 4.56 billion years ago, making it possible a little older than the earth.

“It belongs to a group of asteroids in the head asteroid belt between Mars And Jupiter that we now think that we can bind to a fracture of a much larger one asteroid About 470 million years ago, “said Harris. That destructive event could have taken the McDonough asteroid in an earth-drunking job that would eventually partially see it recovering a house in Henry County.
Harris wants to publish a paper about the composition of the meteorite, together with information about the atmospheric entry later this year. Shards of the McDonough Meteorite will also be shown in the Tellus Science Museum in Cartersville, Georgia.
