    Classification

    Terentia is the namesake of the Terentia family ( 618 ), a small asteroid family of less than a hundred known members of a carbonaceous C-type composition orbiting in the outer main-belt. [4]

    Orbit

    Terentia orbits the Sun at a distance of 2.6–3.3  AU once every 5.01 years (1,832 days). Its orbit has an eccentricity of 0.12 and an inclination of 10° with respect to the ecliptic. [1] The body's observation arc begins at Simeiz, 5 days after its official discovery observation. [15]

    Physical characteristics

    In the SMASS taxonomy, is classified as a Ch-type, a hydrated subtype of the carbonaceous C-type asteroids. [1]

    Naming

    This minor planet was named after Lidiya Terent'eva (1879–1933), female collaborator at the Simeis Observatory. [1]
