17119 Alexisrodrz (provisional designation1999 JP59) is a stony backgroundasteroid from the central region of theasteroid belt, approximately 4 kilometers in diameter.
It was discovered on 10 May 1999, by theLINEAR team at theLincoln Laboratory's Experimental Test Site in Socorro, New Mexico, United States.[8] The asteroid was later named for Alexis Rodriguez, a 2003-awardee of theIntel International Science and Engineering Fair.[2]
Alexisrodrz orbits the Sun in thecentral main-belt at a distance of 2.5–2.8 AU once every 4 years and 3 months (1,565 days). Its orbit has aneccentricity of 0.06 and aninclination of 6° with respect to theecliptic.[1]
The asteroid'sobservation arc begins 7 years prior to its official discovery observation, with aprecovery taken atSteward Observatory (Kitt Peak) in November 1992.[8]
Alexisrodrz has been characterized as a LS-subtype byPan-STARRS' large-scale survey.[7] This subtype is a transitional group from the common stonyS-type to the rare and reddishL-type asteroids.
According to the survey carried out by theNEOWISE mission of NASA's space-basedWide-field Infrared Survey Explorer, Alexisrodrz measures 3.9 kilometers in diameter and its surface has analbedo of 0.18,[4] while theCollaborative Asteroid Lightcurve Link assumes an albedo of 0.10 – a compromise value between thestony (0.20) andcarbonaceous (0.057) asteroids found in the 2.6 to 2.7 AU region of the asteroid belt – and calculates a diameter of 4.6 kilometers with anabsolute magnitude of 14.82.[3]
In January 2011, and September 2013, two rotationallightcurves of Alexisrodrz were obtained from photometric observations made by astronomers at thePalomar Transient Factory in California. Lightcurve analysis gave a concurringrotation period of17.7838 and17.7935 hours with a brightness variation of 0.48 and 0.60magnitude, respectively (U=2/2).[6]
Thisminor planet was named for the 3rd-place winner of the 2003Intel International Science and Engineering Fair, Alexis Rodriguez (born 1986). At the time, he attended the Puerto RicanAurea E. Quiles Claudio High School in Guanica.[2] The approved naming citation was published by theMinor Planet Center on 14 June 2004 (M.P.C. 52172).[9]
