2023 CX1, initially known under temporary designation Sar2667, was a metre-sized asteroid or meteoroid that entered Earth's atmosphere on 13 February 2023 02:59 UTC and disintegrated as a meteor over the coast of Normandy, France along the English Channel.[6] It was discovered less than seven hours before impact, by Hungarian astronomer Krisztián Sárneczky at Konkoly Observatory's Piszkéstető Station in the Mátra Mountains, Hungary.[2][9] 2023 CX1 is the seventh asteroid discovered before impacting Earth and successfully predicted, and the third of those for which meteorites have been recovered. Before it impacted, 2023 CX1 was a near-Earth asteroid on an Earth-crossing Apollo-type orbit.[1]
