Oldest known asteroid impact on Earth dated to 3 billion years
Researchers have identified the oldest known asteroid impact on Earth, dating a site in the Australian outback to 3 billion years ago.
Quick answers
How old is the impact crater?
The crater is confirmed to be 3 billion years old.
Where is the crater located?
It is located in the Australian outback.
How was the age determined?
Researchers used crystalline clocks to confirm the age of the impact site.
The brief
A crater located in Australia has been confirmed as the oldest asteroid impact site discovered on Earth. The impact site is dated to approximately 3 billion years ago, a finding that shifts the previous timeline of known impact structures by half a billion years.
Reports emphasize that this discovery provides new data regarding the history of cosmic collisions on the planet. Future developments will depend on further analysis of the Australian crater and the geological evidence found at the site.
It remains to be seen how this timeline adjustment will influence subsequent studies of impact records.
