The study also determined that the meteorite entered Earth’s atmosphere at a speed of 28.6 kilometres per second, the fastest ever recorded. Chemical and physical analysis revealed Sutter’s Mill to be a relatively rare ‘carbonaceous chondrite’ type of meteorite, and in a near-pristine state.

The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
