From the article:
According to an analysis in February 2020, there's evidence that most of Earth took just 5 million years to come together - several times shorter than current models suggest.
This revision is a significant contribution to our current understanding of planetary formation, suggesting that the mechanisms may be more varied than we think, even between planets of the same type, located in the same neighbourhood - rocky planets, such as Mars and Earth.
