    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]
