1162 Larissa
asteroid
1162 Larissa, provisional designation 1930 AC, is a metallic Hildian asteroid from the outermost regions of the asteroid belt, approximately 43 kilometers in diameter. It was discovered on 5 January 1930, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany. The asteroid was named after the Greek city of Larissa.
Orbit and classification
Larissa belongs to the Hilda group located outermost part of the main-belt. Asteroids in this dynamical group have semi-major axis between 3.7 and 4.2 AU and stay in a 3:2 resonance with the gas giant Jupiter. Larissa, however, is a background asteroid and not a member of the (collisional) Hilda family (101).
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. The body's observation arc begins 15 days after its official discovery observation at Heidelberg.
Physical characteristics
Larissa has been characterized as a metallic M-type asteroid by the Wide-field Infrared Survey Explorer (WISE).

Why this record matters
“1162 Larissa” is worth following because a concise public description often conceals a longer documentary argument. Here, Larissa and asteroid provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q136641. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1162 and 1930.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
