3868 Mendoza, provisional designation 4575 P-L is a stony Vestian asteroid and binary system from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 24 September 1960, by astronomers Cornelis Johannes van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels at Palomar Observatory.[13]

Orbit and characterization

Mendoza orbits the Sun at a distance of 2.1–2.6 AU once every 3 years and 7 months (1,302 days). Its orbit has an eccentricity of 0.10 and an inclination of 8° with respect to the ecliptic.[1]

Satellite

In 2009, a minor-planet moon was discovered. It is provisionally designated S/2009 (3868) 1. The satellite measures 2.01±0.18 km in diameter and orbits Mendoza in a little more than a day.[4][5][6]

Palomar–Leiden

Diameter and albedo

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer (WISE) with its subsequent NEOWISE mission, Mendoza measures between 8.628 and 9.351 kilometers in diameter and its surface has an albedo between 0.1621 and 0.436.[7][8][9] The Collaborative Asteroid Lightcurve Link adopts Petr Pravec's revised WISE data, that is, an albedo of 0.1649 and a rounded diameter of 9.40 kilometers with an absolute magnitude of 12.71.[3][10]

Naming

This minor planet was named in honor of Mexican astronomer Eugenio Mendoza (born 1928), expert in photometry and spectroscopy, member of the IAU and teacher at several Mexican universities.[2][14] The approved naming citation was published by the Minor Planet Center on 1 September 1993 (M.P.C. 22499).[15]
