1998 DK36 is a 30-meter sized asteroid and near-Earth object that is possibly the first Apohele asteroid (Atira) – an asteroid that is always closer to the Sun than Earth – detected. It was first observed on 23 February 1998, by David J. Tholen at Mauna Kea Observatory, Hawaii, but is now considered a lost minor planet.
2002 AT4 is a near-Earth object and potentially hazardous asteroid of the Amor group, approximately 350 meters (1,100 feet) in diameter. It has an eccentric orbit that brings it sometimes close to Earth's orbit, and sometimes halfway between Mars and Jupiter. It is a dark D-type asteroid which means that it may be reddish in color.
(480808) 1994 XL1 is a sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Aten group, approximately 200 meters (700 feet) in diameter. It was discovered on 6 December 1994, by Scottish–Australian astronomer Robert McNaught at Siding Spring Observatory in Australia. It was one of the first asteroids discovered to have a semi-major axis less than Venus.
(614599) 2010 AB78 is a dark asteroid on an eccentric orbit, classified as near-Earth object of the Amor group. It was first observed by the Wide-field Infrared Survey Explorer (WISE) on 12 January 2010. The asteroid measures approximately 1.7 kilometers in diameter and has a low albedo of 0.03, which is rather typical for carbonaceous asteroids.
(163364) 2002 OD20 is an asteroid, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, likely smaller than one kilometer in diameter.
(276033) 2002 AJ129, provisional designation 2002 AJ129, is a Mercury-crossing asteroid. It has the ninth-smallest perihelion of all numbered asteroids, after asteroids such as 2000 BD19, 2004 UL, and 2008 XM. It makes close approaches to all of the inner planets and asteroid 4 Vesta. The asteroid is estimated to be between 0.5–1.2 kilometers (0.3–0.7 mi) across. In January 2018 there was much media hype about this asteroid being classified as a potentially hazardous asteroid, although there is no known threat of an impact for hundreds if not thousands of years. The media has compared the size of the asteroid to the Burj Khalifa in Dubai.
(529366) 2009 WM1, provisional designation 2009 WM1, is a sub-kilometer asteroid and near-Earth object of the Apollo group, approximately 280 meters (920 feet) in diameter. 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.
(101869) 1999 MM, provisional designation 1999 MM is a sub-kilometer asteroid on an eccentric orbit, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group. It was discovered on 20 June 1999, by the Lowell Observatory Near-Earth-Object Search (LONEOS) at its U.S. Anderson Mesa Station in Flagstaff, Arizona. The first observation was made by Catalina Sky Survey just 8 days before its official discovery.
(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.
2014 EC is a 10-meter sized, eccentric asteroid, classified as near-Earth object of the Apollo group that passed within 48,000 miles (77,000 km) of Earth in early March 2014. This was six times closer to the Earth than the Moon. It was first observed on 5 March 2014, by the Catalina Sky Survey at Mount Lemmon Observatory in Arizona, United States. As of 2017, it has not since been observed.
(85989) 1999 JD6 is an Aten asteroid, near-Earth object, and potentially hazardous object in the inner Solar System that makes frequent close approaches to Earth and Venus. On the Earth approach in 2015, it was observed by the Goldstone Solar System Radar and found to be a contact binary with the largest axis approximately 2 kilometers wide, and each lobe about 200–300 meters large. Although 1999 JD6 in its current orbit never passes closer than 0.047 AU to Earth, it is listed as a potentially hazardous object because it is large and might pose a threat in the future.
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.
2017 TD6 is a micro-asteroid, classified as a near-Earth object of the Apollo group, approximately 10–20 meters in diameter. It was first observed by Pan-STARRS at Haleakala Observatory, Hawaii, on 11 October 2017.
2017 VL2 is a micro-asteroid, classified as a near-Earth object of the Apollo group. It was first observed by ATLAS at Mauna Loa Observatory on 10 November 2017, a day after it passed inside the orbit of Earth.
(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.
2018 BF3 is a micro-asteroid, classified as a near-Earth object of the Apollo group, approximately 20 meters (70 ft) in diameter. It was first observed on 20 January 2018, by astronomers of the Catalina Sky Survey at Mount Lemmon Observatory in Arizona, United States, the day after the closest flyby, due to its approach from the direction of the Sun.
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 OU1 is a sub-kilometre asteroid, classified as a near-Earth object of the Apollo group. On 28 August 2019, the object safely passed 1.028 million kilometres from Earth, travelling at around 13 km/s (47,000 km/h).
1979 XB is a lost asteroid with a short observation arc of 3.9 days that cannot be recovered with targeted observations and awaits serendipitous survey observations. It is classified as a near-Earth object and potentially hazardous asteroid of the Apollo group and is estimated to be 660 meters in diameter. The unnumbered minor planet has a poorly constrained orbit and has not been observed in 40 years. It has been listed on the Sentry Risk Table since the list started in 2002. With a cumulative Palermo Technical Impact Hazard Scale of −2.72, the poorly known orbit and assumed size place 1979 XB third on an unconstrained listing of the Sentry Risk Table.
