A meteorite that survived the atmospheric entry and was beaten by the roof of a house in Georgia at the beginning of this year could, according to a scientist from the University of Georgia, had formed in front of Earth, which analyzed fragments of the wandering solar system.
The residents of several southeastern US states were surprised on July 26th when they have a witness to a witness Rare day of the day – bright enough to be registered by an all -round satellite – Loderner earth.
The old Asteroid Schard in the heart of the event survived the intensive friction of the atmospheric entrance to beat a hole through the roof of a house in the city of McDonough, Georgia, and to destroy the ground only 4 meters from an unsuspecting resident.
How old is the McDonough meteorite?
23-gram value of the fragmented meteorite of the name, the meteoroids that reach the ground intact, were later brought to the University of Georgia (Uga), where scientists sat down to struggle for the secrets of its origin. “This special meteor, which has entered the atmosphere, has a long history before it was made on the basis of McDonough, and to understand that we actually have to investigate what the stone is and to determine which group of asteroids he belongs to” said Uga researcher Scott Harris.
The newly named McDonough meteorite is a normal chondrite with low metal (L) – one of the Most old forms of the rock known to exist in the Solar system – That was probably about 4.56 billion years ago and may have made it 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 we can bind to a much larger separation asteroid About 470 million years ago, “said Harris. This destructive event could have brought the McDonough Sanoid into an grounding in the ground that finally restores a house in Henry County.
Harris would like to publish a paper in which the composition of the meteorite together with information about the atmospheric entry later describes this year. The McDonough meteorites’ shards are also exhibited in the Tellus Science Museum in Cartersville, Georgia.
