2012 BX34 is a small Aten asteroid that made one of the closest recorded asteroid close approaches of Earth on 27 January 2012. It passed within 0.0004371 AU (65,390 km; 40,630 mi) of Earth during its closest approach at 15:25 GMT. 2012 BX34 measures around 8 meters (26 ft) across; if it had impacted in 2012, it would have been too small to pass through Earth's atmosphere intact.
2006 BL8 is a sub-kilometer asteroid, classified as near-Earth object of the Apollo group, that flew by Earth on 26 July 2013 at about 9 lunar distances It is reported to be about 48 meters (157 ft) in diameter.
2009 RR micro-asteroid, classified as near-Earth object of the Apollo group. It was discovered on 11 September 2009 by the Catalina Sky Survey at an apparent magnitude of 19.5 using a 0.68-meter (27 in) Schmidt–Cassegrain telescope. 2009 RR was the only asteroid discovered before 2014 that was predicted to potentially pass inside the orbit of the Moon during 2014. The asteroid has an estimated diameter of 26 meters (85 ft) and is listed on the Sentry Risk Table. It is not large enough to qualify as a potentially hazardous object.

2019 BZ3 is a very small near-Earth asteroid of the Apollo group, approximately 6 meters (20 feet) in diameter. It was first observed by the Mount Lemmon Survey on 28 January 2019, just hours after the asteroid's sub-lunar flyby of Earth at less than 0.12 lunar distance.
(481394) 2006 SF6 is a sub-kilometer near-Earth object and potentially hazardous asteroid of the Aten group, approximately 300 meters (1,000 feet) in diameter. It was discovered on 17 September 2006, by the Catalina Sky Survey at Catalina Station in Arizona. On 21 November 2019, it passed Earth at a distance of 11 lunar distances (0.0288 AU), which is the object's closest flyby for centuries. The stony A/S-type asteroid is highly elongated in shape and has a rotation period of 11.5 hours.
2020 HS7 is a very small asteroid classified as a near-Earth object of the Earth-crossing Apollo group. When it was discovered by the Pan-STARRS 2 survey on 27 April 2020, the asteroid was initially calculated to have a 10% chance of impact with Earth before being ruled out by improved orbit determinations from additional observations. Although there is now no risk of impact with Earth, it did make a close approach 42,700 kilometres (26,500 mi) from Earth on 28 April 2020, with a flyby speed of 15.6 kilometres per second (9.7 mi/s) relative to Earth. The asteroid will not make any close encounters within 1 lunar distance (380,000 km; 240,000 mi) of Earth in the next 100 years.
2020 CW is a tiny near-Earth asteroid of the Apollo group, approximately 1 meter (3 ft) in diameter. It was first observed by the Mount Lemmon Survey on 1 February 2020, when it passed Earth very closely at a nominal distance of only 0.041 lunar distances. The object's orbital elements remain highly uncertain.
2022 WM7 is a small near-Earth asteroid that passed about 0.2 lunar distances (77,000 km; 48,000 mi) from Earth's center on 28 November 2022 at 02:24 UTC. It was discovered by the Pan-STARRS 1 survey telescope at Haleakalā Observatory, Hawaii on 26 November 2022.
