1991 BA is a sub-kilometer asteroid, classified as near-Earth object of the Apollo group that was first observed by Spacewatch on 18 January 1991, and passed within 160,000 km (100,000 mi) of Earth. This is a little less than half the distance to the Moon. With a 5-hour observation arc the asteroid has a poorly constrained orbit and is considered lost. It could be a member of the Beta Taurids.
(179806) 2002 TD66 (also written 2002 TD66) is a sub-kilometer asteroid, classified as near-Earth object of the Apollo group. It was discovered on 5 October 2002, by the LINEAR project at Lincoln Laboratory's ETS in Socorro, New Mexico. It was announced on 7 October 2002 and appeared later that day on the JPL current risk page.
1994 WR12 is an asteroid and near-Earth object approximately 130 meters (430 feet) in diameter. As a member of the Aten group almost all of its orbit is closer to the Sun than Earth is. On 24 November 1994 it passed about 374100 km from the Moon. First imaged at Kitami Observatory on 26 November 1994, it was discovered two nights later by American astronomer Carolyn S. Shoemaker at Palomar Observatory on 28 November 1994. The asteroid then went unobserved from 1994 until it was recovered by Mauna Kea in March 2016. It was removed from the Sentry Risk Table on 2 April 2016.
(6491) 1991 OA is a highly eccentric, stony asteroid, classified as near-Earth object and potentially hazardous asteroid, approximately half a kilometer in diameter. It was discovered on 16 July 1991, by American astronomer Henry E. Holt at the U.S. Palomar Observatory in California.

After its discovery by the Catalina Sky Survey at the Catalina Station in Arizona, United States, this potentially hazardous asteroid was briefly listed at a Torino Scale of 1 and a cumulative Palermo Scale of −0.87. It was removed from the Sentry Risk Table on 26 June 2013.
(511002) 2013 MZ5, provisional designation 2013 MZ5, is a sub-kilometer asteroid, classified as a near-Earth object of the Amor group, estimated to measure approximately 300 meters (1,000 feet) in diameter. It was discovered on 18 June 2013, by astronomers with the Pan-STARRS survey at Haleakala Observatory on the island of Maui, Hawaii, in the United States. It was the 10,000th near-Earth object ever discovered.
(523662) 2012 MU2, provisional designation 2012 MU2, is a sub-kilometer asteroid on an eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group. It was discovered on 18 June 2012 by astronomers of the Catalina Sky Survey at an apparent magnitude of 19.9 using a 0.68-meter (27 in) Schmidt–Cassegrain telescope. It has an estimated diameter of 240 meters (790 ft). The asteroid was listed on Sentry Risk Table with a Torino Scale rating of 1 on 23 June 2012.
(89958) 2002 LY45 is an asteroid, classified as near-Earth object of the Apollo group that is also a Mercury-crosser, Venus-crosser, and Mars-crosser. It was discovered by the LINEAR program on 14 June 2002.
2012 UE34 is a sub-kilometer asteroid, classified as a near-Earth object of the Apollo group, approximately 70 meters (230 feet) in diameter. It was first observed on 18 October 2012, by Pan-STARRS at Haleakala Observatory on the island of Maui, Hawaii, in the United States. The object was removed from the Sentry Risk Table on 29 December 2013. On 8 April 2041 it will pass Earth at a nominal distance of 0.0007329 AU (110,000 km; 68,000 mi). Due to its presumed small size, it does not qualify as a potentially hazardous asteroid, despite its low Earth MOID.
(415029) 2011 UL21, provisional designation 2011 UL21, is an Apollo class potentially hazardous asteroid discovered on October 17, 2011, by the Catalina Sky Survey project.

(585310) 2017 YZ1, provisional designation: 2017 YZ1, is a sub-kilometer asteroid on an eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 250 meters (800 feet) in diameter. It was first observed on 20 December 2017, by astronomers with the Mount Lemmon Survey at Mount Lemmon Observatory near Tucson, Arizona, in the United States. On 29 January 2018, it passed Earth at 125 lunar distances.

Two days later, the asteroid crossed the orbit of the Moon and made a very close approach to Earth.
(85182) 1991 AQ, provisional designation 1991 AQ, is a stony asteroid on a highly eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.1 kilometers in diameter. It was discovered on 14 January 1991, by American astronomer Eleanor Helin at the Palomar Observatory in California. Based on its brightness variation of 0.69 magnitude, this Q-type asteroid is likely elongated. It belongs to the small group of potentially hazardous asteroids larger than one kilometer.
2016 AZ8 is a sub-kilometer asteroid and near-Earth object of the Apollo group, at least 400 meters (1,300 feet) in diameter. It was first observed on 3 January 2016, by the WISE telescope with precovery images found back in 2012.
2019 AS5 is a near-Earth asteroid that passed close by the Earth on 8 January 2019. It passed within 0.04 lunar distances or 15,000 kilometers of the center of the Earth, 8600 km from the surface. It was discovered by the Mt. Lemmon Survey 9 hours after closest approach. It is estimated to be about 1–2 metres (3–7 feet) in diameter.
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 EB5 was a small, two-metre Apollo near-Earth asteroid that disintegrated in Earth's atmosphere at 21:22 UTC on 11 March 2022, over the Arctic Ocean southwest of the Norwegian island Jan Mayen. With an atmospheric entry speed of 18 km/s (11 mi/s), the asteroid's impact generated a 4-kiloton-equivalent fireball that was detected by infrasound from Greenland and Norway. A bright flash possibly associated with the event was reported by observers from Northern Iceland.
