The asteroid was discovered by Russian astronomer Grigory Neujmin at Simeiz Observatory on 17 September 1930. 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. 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. The body's observation arc begins at Simeiz, 5 days after its official discovery observation. Physical characteristics In the SMASS taxonomy, is classified as a Ch-type, a hydrated subtype of the carbonaceous C-type asteroids. Naming This minor planet was named after Lidiya Terent'eva (1879–1933), female collaborator at the Simeis Observatory. References 30em 2017-03-29 last obs.
