A meteorite that fell on a house in the US is older than the Earth, scientists say.
The celestial body streaked through the skies before exploding in Georgia on June 26, NASA confirmed.
Scientists at the University of Georgia examined a piece of rock that pierced the roof of a house in McDonough. Based on the type of meteorite, they determined that it must have formed 4.56 billion years ago, making it 20 million years older than our planet.
There were hundreds of reports from residents of Georgia and neighboring states and a loud bang as the fireball tore through the skies.
The rock quickly shrank in size and speed, but continued to fly at at least 1 km/s.
Using optical and electron microscopes, Scott Harris of the University of Georgia and his team said it was a chondrite, one of the most common stony meteorites.
Called the McDonough meteorite, it is now the 27th to hit Georgia. "This is something you would expect once every few decades, not a few times in 20 years," Harris said.
He hopes to publish his research on the asteroid's composition and velocity, which will help understand the threat from other asteroids.
