    (68950) 2002 QF15 is a stony asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, that measures approximately 2 kilometers in diameter. It was discovered on 27 August 2002, by the LINEAR project at Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico, United States. [2]

    Orbit and classification

    2002 QF15 is a S-type asteroid that orbits the Sun at a distance of 0.7–1.4  AU once every 1 years and 1 month (397 days). Its orbit has an eccentricity of 0.34 and an inclination of 25° with respect to the ecliptic. [1] Taken at Palomar Observatory in 1955, a first precovery from the during the Digitized Sky Survey extends the body's observation arc by 47 years prior to its official discovery observation at Socorro. [2]

    It has an Earth minimum orbital intersection distance 0.0063 AU (942,000 km), which translates into 2.6 LD. [1]

    Physical characteristics

    In June 2006, a rotational lightcurve of 2002 QF15 was obtained from photometric observation taken by American astronomer Brian Warner at his Palmer Divide Observatory in Colorado. Lightcurve analysis gave a rotation period of 47 hours with a brightness variation of 0.35 magnitude ( U=2 ), [5] superseding a lightcurve previously obtained by Czech astronomer Petr Pravec at Ondřejov Observatory in 2003, which gave a shorter period of 29 hours and an amplitude of 0.3 magnitude ( U=2- ). [lower-alpha 1]

    According to the survey carried out by the Japanese Akari satellite, the asteroid measures 1.12 kilometers in diameter and its surface has an albedo of 0.428, [3] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.040 and calculates a diameter of 3.49 kilometers with an absolute magnitude of 16.4. [4]

    Numbering and naming

    This minor planet was numbered by the Minor Planet Center on 10 September 2003. [6] As of 2018, it has not been named. [2]
