(33001) 1997 CU29, also written as (33001) 1997 CU29 is a cold classical Kuiper belt object, or cubewano. It has a perihelion (closest approach to the Sun) at 41.6 AU and an aphelion (farthest approach from the Sun) of 45.1 AU. 1997 CU29 is about 280 km in diameter. It was discovered on February 6, 1997, by David C. Jewitt, Jane X. Luu, Chad Trujillo, and Jun Chen at the Mauna Kea Observatory, Hawaii.
(85627) 1998 HP151, provisional designation 1998 HP151, is a trans-Neptunian object from the classical Kuiper belt, located in the outermost region of the Solar System. The cubewano belongs to the cold population. It has a perihelion (closest approach to the Sun) at 40.297 AU and an aphelion (farthest approach from the Sun) of 48.306 AU. It is about 146 km in diameter. It was discovered on 28 April 1998, at the Mauna Kea Observatory, Hawaii.
(85633) 1998 KR65, provisional designation 1998 KR65, is a trans-Neptunian object from the classical Kuiper belt, located in the outermost region of the Solar System. The cubewano belongs to the cold population. It has a perihelion (closest approach to the Sun) at 42.385 AU and an aphelion (farthest approach from the Sun) at 44.859 AU. It is about 192 km in diameter. It was discovered on 29 May 1998, by Gary M. Bernstein.
2006 QH181, also written as 2006 QH181, is a trans-Neptunian object (TNO) in the scattered disc. Its orbit is currently too poorly determined (U=6) to know whether it is in a resonance with Neptune.
(523639) 2010 RE64, provisional designation 2010 RE64, is a trans-Neptunian object in the scattered disc located in the outermost region of the Solar System, approximately 570 kilometers (350 miles) in diameter. It was discovered on 11 July 2010 by the Pan-STARRS-1 survey at the Haleakala Observatory, Hawaii, in the United States.
(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.
(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.
(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.
(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.
2011 GA is a small asteroid that is a Near-Earth object and an Apollo asteroid.
2007 UW1 is a sub-kilometer asteroid that is a near-Earth object of the Aten group.
