    17119 Alexisrodrz, provisional designation 1999 JP59, is a stony asteroid from the middle region of the asteroid belt, approximately 4 kilometers in diameter. It was discovered by the Lincoln Near-Earth Asteroid Research team (LINEAR) at the U.S. Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico, on 10 May 1999.[8]

    The asteroid orbits the Sun at a distance of 2.5–2.8 AU once every 4 years and 3 months (1,565 days). Its orbit has an eccentricity of 0.06 and an inclination of 6° with respect to the ecliptic.[1] The first precovery was obtained at Steward Observatory (Kitt Peak) in 1992, extending the asteroid's observation arc by 7 years prior to its discovery.[8]

    The S-type asteroid is also classified as a LS-subtype by Pan-STARRS' large-scale survey.[7] This subtype is a transitional group from the generic stony S-type to the rather rare and strongly reddish L-type asteroids. According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 3.9 kilometers in diameter and its surface has an albedo of 0.18,[4] while the Collaborative Asteroid Lightcurve Link assumes an untypically low albedo of 0.10 and calculates a diameter of 4.6 kilometers.[3]

    In January 2011, and September 2013, two rotational light-curves of this asteroid were obtained from photometric observations made by the wide-field survey at the U.S Palomar Transient Factory in California. The light-curves gave a concurring rotation period of 17.7935±0.0290 and 17.7838±0.0290 hours with a brightness variation of 0.60 and 0.48 in magnitude, respectively (U=2/2).[6]

    The minor planet was named for the 3rd-place winner of the 2003 Intel International Science and Engineering Fair, Alexis Rodriguez (b.1986). At the time, he attended the Puerto Rican Aurea E. Quiles Claudio High School in Guanica.[2] Naming citation was published on 14 June 2004 (M.P.C. 52172).[9]
