Citando:
"The mineral came from the Uakit meteorite, named for the Russian location where it was found. Scientists recently presented their discovery of the meteorite's new mineral, named uakitite, at the Annual Meeting of the Meteoritical Society in Moscow.
The researchers found that more than 98 percent of the meteorite consists of kamacite, an alloy of iron and 5 to 10 percent nickel, that's formed in space and is found only in meteorites, which are rocks that fall from space to Earth's surface. The remaining 1 to 2 percent of the meteorite consists of just over a dozen minerals that, for the most part, are exclusively formed in space. On top of that, the composition of the extraordinary space rock suggests that it must have formed under brutally hot temperatures, well over 1,800 degrees Fahrenheit (1,000 degrees Celsius), the researchers said.
