    Classification and orbit

    Davidweilla orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 5 months (1,237 days). Its orbit has an eccentricity of 0.19 and an inclination of 6° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation at Algiers.[4]

    Physical characteristics

    Diameter and albedo

    According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Davidweilla measures 6.884 kilometers in diameter and its surface has an albedo of 0.130.[3]

    Lightcurves

    As of 2017, no rotational lightcurve of Davidweilla has been obtained. The body's rotation period and shape remain unknown.[1][5]

    Naming

    This minor planet was named after David Weill, at the Sorbonne University in Paris. He was a member of the Academy of sciences. The official naming citation was published by Paul Herget in The Names of the Minor Planets (H 99).[2]
