1189 Terentia, provisional designation {{mp|1930 SG}}, is a carbonaceous Terentian asteroid from the outer regions of the asteroid belt, approximately 56 kilometers in diameter and the namesake of its family. 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 ({{small|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.
