23327 Luchernandez (provisional designation2001 BE31) is a Florianasteroid from the inner regions of theasteroid belt, approximately 2 kilometers in diameter. It was discovered on 20 January 2001, by astronomers of theLINEAR program at theLincoln Laboratory's Experimental Test Site near Socorro, New Mexico, United States.[2] The asteroid was named forISEF awardee Lucero Hernandez.[2]

Orbit and classification

[edit]

Luchernandez is a member of theFlora family (402),[4][5] a giantasteroid family and the largest family of stony asteroids in the main-belt.[10]: 23  It orbits the Sun in theinner asteroid belt at a distance of 2.1–2.6 AU once every 3 years and 7 months (1,305 days;semi-major axis of 2.34 AU). Its orbit has aneccentricity of 0.11 and aninclination of 6° for theecliptic.[1]

The body'sobservation arc begins with aprecovery published by theDigitized Sky Survey that was taken atPalomar Observatory in August 1992, more than 18 years before its official discovery observation at Socorro.[2]

Physical characteristics

[edit]

Luchernandez is an assumedS-type asteroid,[4] which agrees with the overallspectral type for members of the Flora family.[10]: 23 

Rotation period

[edit]

In December 2007, a rotationallightcurve of Luchernandez was obtained from photometric observations by Slovak astronomersAdrián Galád andLeonard Kornoš at theModra Observatory. Lightcurve analysis gave arotation period of 4.933 hours with a brightness variation of 0.50magnitude (U=2+).[8] A high brightness amplitude is indicative of an elongated, non-spherical shape. Alternative period solutions that give 5.49 hours or longer are less likely.[8]

Diameter and albedo

[edit]

According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, Luchernandez measures 2.475 kilometers in diameter and its surface has analbedo of 0.2399.[6][7]

TheCollaborative Asteroid Lightcurve Link assumes an identical albedo of 0.24 – derived from8 Flora, the family'sparent body – and calculates a diameter of 2.26 kilometers based on anabsolute magnitude of 15.4.[4]

Naming

[edit]

Thisminor planet was named after Mexican student Lucero Hernandez (born 1989), who won second place in the 2007Intel International Science and Engineering Fair for her computer science team project.[3] The official naming citation was published by theMinor Planet Center on 28 August 2007 (M.P.C. 60505).[11]
