New research indicates that the Earth and moon are 60 million years older than previously estimated. That is, the violent collision believed to have created the moon and gave Earth its current form occurred just 40 million years after the solar system formed some 4.5 billion years ago.
Previous estimates had the Earth and the moon forming 100 million years after the solar system’s formation.
How confident are the researchers of their finding? Not super-confident. They acknowledged that the 60 million year figure may be off by as much as 20 million years.
