CNEOS 2014-01-08, also known as Interstellar meteor 1 (IM1),[2][3][4] was a 0.45 m (1.5 ft) meteor that impacted Earth on 8 January 2014 near the northeast coast of Papua New Guinea. It was claimed to be an interstellar object in a 2019 preprint by astronomers Amir Siraj and Abraham Loeb,[2][5] and this was published in 2022.[6][7][8][9] This was confirmed by the U.S. Space Command in 2022 based on the object's velocity relative to the Sun.[10][11][12][13][14][15][7] Other astronomers doubt this,[16][17][18][19][20][21] and still other experts found Earth-related explanations for the purported meteorite impact instead.[22]
