}}{{mp|(143651) 2003 QO|104}}, provisional designation {{mp|2003 QO|104}}, is a stony asteroid, slow rotator and suspected tumbler on a highly eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Amor and Apollo group, respectively. It was discovered on 31 August 2003, by astronomers of the Near-Earth Asteroid Tracking program at the Haleakala Observatory in Hawaii, United States.[1] The Q-type asteroid has a rotation period of 114.4 hours and possibly an elongated shape. It measures approximately {{convert|2.3|km|mi|abbr=off|sigfig=2|sp=us}} in diameter and belongs the largest potentially hazardous asteroids known to exist.[30]

Orbit and classification

{{mp|2003 QO|104}} is a member of the Apollo group of asteroids, which are Earth-crossing asteroids. They are the largest group of near-Earth objects with approximately 10 thousand known members. As it just grazes the orbit of Earth, the Minor Planet Center (MPC), groups it to the non-Earth crossing Amor asteroids.[1]

It orbits the Sun at a distance of 1.015–3.3 AU once every 3 years and 1 month (1,140 days; semi-major axis of 2.14 AU). Its orbit has an eccentricity of 0.52 and an inclination of 12° with respect to the ecliptic. The body's observation arc begins with a precovery taken at the Siding Spring Observatory on in July 1981, more than 18 years prior to its official discovery observation at Haleakala.[1]

Close approaches

The asteroid has an Earth minimum orbital intersection distance of {{convert |0.0042 |AU |km mi |abbr=on |lk=off |sigfig=3}}, which corresponds to 1.6 lunar distances and makes it a potentially hazardous asteroid due to its sufficiently large size. On the Torino Scale, this object was rated level 1 in early October 2003,[35] and removed on 13 October 2003.[36]

On 18 May 1985, it passed Earth at a nominal distance of {{convert|0.00709|AU|LD|abbr=on|sigfig=3}} which translates into {{convert|1060648|km|mi|abbr=on|sigfig=3}} and made another approach in June 2009 at a much larger distance of 37 LD.[37] In 2034, 2037 and 2062, it will pass Earth at a distance of 0.18 AU, 0.44 AU and 0.045 AU, respectively. It frequently approaches Jupiter at 1.7–2.0 AU as well.[37]

Physical characteristics

{{mp|2003 QO|104}} has been characterized as an uncommon Q-type asteroid,[18] that falls into the larger stony S-complex.[8]

Slow rotator and tumbler

Several rotational lightcurve of this asteroid were obtained from photometric observations during its close approach to the Earth in 2009.[11][12][13] Analysis of the best-rated lightcurve – obtained by Brian Warner at his Palmer Divide Observatory in collaboration with Robert Stephens and Albino Carbognani – gave a well-defined rotation period of 114.4 hours with a high brightness amplitude of 1.60 magnitude ({{small|U=3}}), which is indicative of an elongated shape.[13]{{efn|name=lightcurve-plot-Warner}} With a period of more than 100 hours, {{mp|2003 QO|104}} is a slow rotator as most asteroids typically rotate every 2 to 20 hours once around their axis. The asteroid also shows several characteristics of a non-principal axis-rotation, which is commonly known as tumbling.[12][13]

This asteroid has also been studied by radar at the Goldstone and Arecibo observatories by Lance Benner and Mike Nolan.[13]{{efn|name=radar-observations-Goldstone}}

Diameter and albedo

According to post-cryogenic observations made by the Spitzer Telescope during the ExploreNEOs survey, this asteroid measures 2.29 and 2.31 kilometers in diameter and its surface has an albedo between 0.13 and 0.14,[9][10][16] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 1.88 kilometers based on an absolute magnitude of 16.0.[8]

Naming

This minor planet was numbered by the MPC on 5 December 2006 ({{small|M.P.C. 58189}}).[52] As of 2018, it has not been named.[1]
