It was discovered on 31 August 2003, by astronomers of the Near-Earth Asteroid Tracking program at the Haleakala Observatory in Hawaii, United States. The Q-type asteroid has a rotation period of 114.4 hours and possibly an elongated shape. It measures approximately 2.3 km mi off 2 us in diameter and is among the largest potentially hazardous asteroids known to exist. Orbit and classification 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. 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. Close approaches The asteroid has an Earth minimum orbital intersection distance of 0.0042 AU km mi on off 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, and removed on 13 October 2003. On 18 May 1985, it passed Earth at a nominal distance of 0.00709 AU LD on 3 which translates into 1060648 km mi on 3 and made another approach in June 2009 at a much larger distance of 37 LD. 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. Physical characteristics 2003 QO 104 has been characterized as an uncommon Q-type asteroid, that falls into the larger stony S-complex. Slow rotator and tumbler Several rotational lightcurve of this asteroid were obtained from photometric observations during its close approach to the Earth in 2009. 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 (U=3), which is indicative of an elongated shape.lightcurve-plot-Warner With a period of more than 100 hours, 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. This asteroid has also been studied by radar at the Goldstone and Arecibo observatories by Lance Benner and Mike Nolan.radar-observations-Goldstone Diameter and albedo According to post-cryogenic observations made by the Spitzer Space 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, 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. Naming This minor planet was numbered by the MPC on 5 December 2006 (M.P.C. 58189). As of 2018, it has not been named.
