Then, by measuring the meteorite's lead isotopes, they determined its age to be approximately 4.564 billion years, similar to inner solar system basalts, which are present in planetary crusts.

Analysis of meteorite Northwest Africa 12264 suggests that we may have to alter our timeline of the early Solar System, potentially changing our models of planet formation. In 2018, a small ...

Scientists have thought that our solar system's inner rocky planets — Mercury, Venus, Earth and Mars —formed first (around 4.566 billion years ago), while gas giants and icy bodies in the ...

A small, inconspicuous meteorite may be about to change our understanding of how and when our solar system formed. Tiny shavings from the meteorite Northwest Africa 12264 are challenging the long ...

That appears to have been a very good move, as upon further analysis, the 50.8-gram (1.8-ounce) chunk of rock appears to provide evidence that we have the timeline of the early Solar System a ...
