2024 BX₁, previously known under its temporary designation Sar2736, was a metre-sized asteroid or meteoroid that entered Earth's atmosphere on 21 January 2024 00:33 UTC and disintegrated as a meteor over Berlin. It was discovered less than three hours before impact by Hungarian astronomer Krisztián Sárneczky at Konkoly Observatory's Piszkéstető Station in the Mátra Mountains, Hungary. The fireball was observed by the cameras of the AllSky7 and Fripon networks. 2024 BX₁ is the eighth asteroid discovered before impacting Earth, and is Sárneczky's third discovery of an impacting asteroid. Before it impacted, 2024 BX₁ was a near-Earth asteroid on an Earth-crossing Apollo-type orbit.

Meteorite fragments of 2024 BX₁ were found five days after it entered the Earth's atmosphere. It was later found to be an aubrite, a rare group of meteorites.
