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]
