512),^[4] a well-established central asteroid family of more than 1,200 carbonaceous asteroids. The family's namesake is 668 Dora. It is alternatively known as the "Zhongolovich family", named after its presumably largest member 1734 Zhongolovich. The Dora family may also contain a subfamily.^[6][7]

semi-major axis of 2.8 AU). Its orbit has an eccentricity of 0.21 and an inclination of 7° with respect to the ecliptic.^[3] The body's observation arc begins with a precovery taken at Palomar in July 1954, or six years prior to its official discovery observation.^[1]

survey designation "P-L" stands for Palomar–Leiden, named after Palomar Observatory and Leiden Observatory, which collaborated on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory where astrometry was carried out. The trio are credited with the discovery of several thousand asteroid discoveries.^[8]

rotation period, pole and shape remain unknown.^[3]

albedo of 0.051, typical for a carbonaceous asteroid.^[5]
