    2024 BX 1 is the eighth asteroid discovered before impacting Earth, and is Sárneczky's third discovery of an impacting asteroid. Before it impacted, 2024 BX 1 was a near-Earth asteroid on an Earth-crossing Apollo-type orbit. The bolide was studied in June 2024. It had a steep entry of 75.6° and an entry speed of 15.20 km/s.

    Near-Earth object detection technology began to improve around 1998, so objects being detected as of 2004 could have been missed only a decade earlier due to a lack of dedicated near-Earth astronomical surveys. As sky surveys improve, smaller and smaller asteroids are regularly being discovered.

    en.wikipedia.org/wiki/2023_BU

    2023 BU is a near-Earth object that passed 9,967 ± 1 km (6,193.21 ± 0.62 mi) from the centerpoint of Earth around 27 January 2023 00:29 UT. [3] Since Earth's radius is about 6,378 km (3,963 mi), it was expected to pass approximately 3,589 ± 1 km (2,230.10 ± 0.62 mi) from the surface of Earth over the southern tip of South America. [7]

    Near-Earth comets (NECs) are objects in a near-Earth orbit with a tail or coma made up of dust, gas or ionized particles emitted by a solid nucleus. Comet nuclei are typically less dense than asteroids but they pass Earth at higher relative speeds, thus the impact energy of a comet nucleus is slightly larger than that of a similar-sized ...

    The observations were conducted at twilight to search for undiscovered minor planets situated at low elongations from the Sun. [9] The object was discovered at apparent magnitude 19, with a solar elongation of 37 degrees when it was on the far side of the Sun at an Earth distance of 1.3 AU (190 million km). [1]

    In addition, it discovered 416 new objects and about a quarter of those were near-Earth objects classification. [60] As of July 2024, WISE / NEOWISE statistics lists a total of 399 near-Earth objects (NEOs), including 2016 WF 9 and C/2016 U 1, discovered by the spacecraft: [34] 365 NEAs (subset of NEOs) 66 PHAs (subset of NEAs) 34 comets
