1162 Larissa, provisional designation 1930 AC, is a metallic Hildian
Heidelberg Observatory in southwest Germany.[14] The asteroid was named after the Greek city of Larissa.[3]
Orbit and classification
Larissa belongs to the
101).[5]
The asteroid orbits the Sun at a distance of 3.5–4.4 AU once every 7 years and 10 months (2,856 days). Its orbit has an eccentricity of 0.11 and an inclination of 2° with respect to the ecliptic.[1] The body's observation arc begins 15 days after its official discovery observation at Heidelberg.[14]
Physical characteristics
Larissa has been characterized as a metallic
Tholen classification, the asteroid a primitive P-type asteroid, which typically have lower albedos than those measured by WISE and Akari (see below).[1]
