The McDonough meteorite, which crashed into a home in Georgia, has been dated to be 4.56 billion years old, making it 20 million years older than our planet. Researchers at the University of Georgia are now analyzing its structure to understand the potential dangers of future asteroid impacts.

Ancient Meteorite Found in Georgia Home Offers Glimpse into Early Solar System
Scientists reveal that a meteorite that crashed into a Georgia residence is older than Earth, providing insights into the solar system's formation.
A remarkable discovery was made following a meteoric event that captivated residents of McDonough, Georgia, where a meteorite recently burst into the atmosphere and impacted a home. According to scientists from the University of Georgia, this ancient space rock—a fragment of which pierced the roof—dates back approximately 4.56 billion years, thus predating Earth by around 20 million years.
The meteorite, designated the McDonough meteorite, streaked across the skies on June 26, 2023, and was witnessed by residents across various states. Eyewitness accounts noted a bright fireball followed by a loud boom as the rock traversed the atmosphere at speeds in excess of 1 km per second. After further examination, researchers confirmed that multiple fragments collected from the damaged home are classified as chondrites, a prevalent category of stony meteorites.
Scott Harris, a geologist on the team, remarked on the historical significance of such findings. "This particular meteor has a long history before it made it to the ground of McDonough," he explained. He highlighted the increased frequency of meteorite recoveries in recent decades, attributing this to advancements in technology and a more watchful public.
Homeowner reports indicate ongoing discovery of micro-particles, likened to space dust remnants, scattered around the property. Research on the McDonough meteorite is expected to be published soon, with Harris and his team delving into the composition and velocity of the object. The insights gleaned could be invaluable in assessing global strategies for asteroid threat mitigation.
As noted by Harris, “One day there will be an opportunity, and we never know when it’s going to be, for something large to hit and create a catastrophic situation. If we can guard against that, we want to.”
This incident marks the 27th meteorite recovery from Georgia, showcasing the evolving landscape of meteorite studies and the potential for significant findings in the future.
