An interstellar object exploded over Earth in 2014, declassified government data reveal · 5

The object, a small meteorite measuring just 1.5 feet (0.45 meter) across, slammed into Earth's atmosphere on Jan. 8, 2014, after traveling through space at more than 130,000 mph (210,000 km/h) — a speed that far exceeds the average velocity of meteors that orbit within the solar system, according to a 2019 study of the object published in the preprint database arXiv.

That 2019 study argued that the wee meteor's speed, along with the trajectory of its orbit, proved with 99% certainty that the object had originated far beyond our solar system — possibly "from the deep interior of a planetary system or a star in the thick disk of the Milky Way galaxy," the authors wrote. But despite their near certainty, the team's paper was never peer-reviewed or published in a scientific journal, as some of the data needed to verify their calculations was considered classified by the U.S. government, according to Vice.
