- (15760)_1992_QB1 abstract "(15760) 1992 QB1, also written (15760) 1992 QB1, was the first trans-Neptunian object to be discovered after Pluto and Charon. It was discovered in 1992 by David C. Jewitt and Jane X. Luu at the Mauna Kea Observatory, Hawaii. It is a classical Kuiper belt object and gave rise to the name cubewano for this kind of object, after the \"QB1\" portion of its designation. Decoding its provisional designation, \"QB1\" reveals that it was the 27th object found in the second half of August of that year. Over 1,500 further objects have been found beyond Neptune, a good number of which are classical Kuiper belt objects.The discoverers suggested the name \"Smiley\" for (15760) 1992 QB1, but the name was already used for an asteroid 1613 Smiley, named after the American astronomer Charles Hugh Smiley. It has received the number 15760 and remains unnamed; it is normally referred to simply as \"QB1\", even though this is technically ambiguous without the year of discovery.".

It is not a detached object, since its perihelion (closest approach to the Sun) is under the influence of Neptune. Light-curve-amplitude analysis suggests that it is a spheroid. Tancredi presents \"in the form of a decision tree, the set of questions to be considered in order to classify an object as an icy 'dwarf planet'.\" They find that (15874) 1996 TL66 is very probably a dwarf planet.

It is a potentially hazardous asteroid as its orbit crosses that of Earth.In 2011, NASA considered sending the unmanned spacecraft Deep Impact toward the asteroid with the aim of performing a flyby in 2020. It was uncertain whether Deep Impact carried sufficient fuel for this operation.On November 24, 2011 and October 4, 2012, the space probe's thrusters were fired briefly for two trajectory correction maneuvers that targeted Deep Impact for an encounter with 2002 GT in 2020, possibly within a distance of no more than 400 kilometers. However, funding for the flyby mission was not guaranteed. In June 2013 the asteroid was observed in radar by the Arecibo Observatory.However, on August 8, 2013 NASA lost communication with the spacecraft, and on September 20, 2013, NASA abandoned further attempts to contact the craft.

- (388188)_2006_DP14 abstract "(388188) 2006 DP14 is a near-Earth object that passed about 6.2 lunar distances from Earth on 10 February 2014, and is considered a potentially hazardous object. On the night of February 11, 2014 NASA scientists conducted a radar imaging session using the Goldstone 70 metres (230 ft) dish. These observations revealed its basic shape and size; it appears to be about 400×200 m. Amateur and professional astronomers helped track the asteroid in the preceding days, so they would know just where to point the large antenna.".
- (391211)_2006_HZ51 abstract "(391211) 2006 HZ51 is an 800 meter in diameter asteroid discovered on 27 April 2006 by the Catalina Sky Survey that with a 1.1 day observation arc was thought to have a 1 in 6 million chance of hitting Earth on 21 June 2008. Further refinement of the orbit quickly eliminated the risk. The preliminary orbit solution was at first thought to have a period of 7 years and a perihelion of ~1.1 AU. [MPEC 2006-H58, 28 April 2006, 2-day orbit].".
