“23327 Luchernandez”的意思、由来-开放百科全书

The body's observation arc begins with a precovery published by the Digitized Sky Survey that was taken at Palomar Observatory in August 1992, more than 18 years prior to its official discovery observation at Socorro.^[2]

Physical characteristics

Luchernandez is an assumed S-type asteroid,^[4] which agrees with the overall spectral type for members of the Flora family.^[23]{{rp|23}}

Rotation period

In December 2007, a rotational lightcurve of Luchernandez was obtained from photometric observations by Slovak astronomers Adrián Galád and Leonard Kornoš at the Modra Observatory. Lightcurve analysis gave a rotation period of 4.933 hours with a brightness variation of 0.50 magnitude ({{small|U=2+}}).^[10] A high brightness amplitude is indicative of an elongated, non-spherical shape. Alternative period solutions that give a period of 5.49 hours or longer are less likely.^[10]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Luchernandez measures 2.475 kilometers in diameter and its surface has an albedo of 0.2399.^[8]^[9]

The Collaborative Asteroid Lightcurve Link assumes an identical albedo of 0.24 – derived from 8 Flora, the family's parent body – and calculates a diameter of 2.26 kilometers based on an absolute magnitude of 15.4.^[4]

Naming

This minor planet was named after Mexican student Lucero Hernandez (born 1989), who won second place in the 2007 Intel International Science and Engineering Fair for her computer science team project.^[3] The official naming citation was published by the Minor Planet Center on 28 August 2007 ({{small|M.P.C. 60505}}).^[34]
