[10] [11] [12] Two 10-micron diamond grains were found in meteorite fragments recovered before any rain fell as the rain would degrade the purity of the meteorites for scientific study. [13] In primitive meteorites like Sutter's Mill, some grains survived from what existed in the cloud of gas, dust and ice that formed the Solar System .
This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
A sixth stone (N06) weighing 23.7 grams was found by the Kane family on November 11. [7] More massive 1 kilogram (2.2 lb) fragments may have fallen near Sonoma with any 10 kilograms (22 lb) fragments possibly falling near Yountville. [8] This was the second significant meteorite in California in 2012, the first being the Sutter's Mill meteorite.
The meteorite, S2, was first discovered in 2014. It hit the planet about 3.26 billion years ago and is estimated to have been up to 200 times larger than the space rock that later killed the ...
In 1987, the farm owner donated the meteorite and the site where it lies to the state for educational purposes. Later that year, the government opened a tourist centre at the site.

But that was far from the largest meteorite to strike our planet. One up to 200 times bigger landed 3.26 billion years ago, triggering worldwide destruction at an even greater scale.
