Picture MUST credit: University of Georgia A meteorite that smashed into a house in June this year has been found to be 20 million years older than the Earth. It came from an estimated one tonne meteor that disintegrated in the sky over the US city of Atlanta Georgia. It sent a cherry tomato-sized fragment shooting through the roof of a home. Using optical and electron microscopes, geologists at the University of Georgia revealed the meteorite was likely over 4.56 billion years old. That's 20 million years older than Earth. It was named the McDonough Meteorite after the residential area of Atlanta called McDonough where it fell. It was examined by University of Georgia planetary geologist Scott Harris. He said: "This particular meteor that entered the atmosphere has a long history before it made it to the ground/ "In order to totally understand that, we actually have to examine what the rock is and determine what group of asteroids it belongs to.” Using optical and electron microscopy to analyse the fragment, Harris said the meteorite formed 4.56 billion years ago, older than the Earth itself.
