835 Olivia (prov. designation:A916 SHor1916 AE) is a darkbackground asteroid from the outer regions of theasteroid belt. It was discovered by German astronomerMax Wolf at theHeidelberg-Königstuhl State Observatory on 23 September 1916.[1] The carbonaceousC-type asteroid measures approximately 35 kilometers (22 miles) in diameter, and is one of few low-numbered asteroids with an undeterminedrotation period. Any reference to the origin of the asteroid's name is unknown.[2]
Olivia is a non-family asteroid of the main belt'sbackground population when applying thehierarchical clustering method to itsproper orbital elements.[4][5] It orbits the Sun in theouter asteroid belt at a distance of 2.9–3.5 AU once every 5 years and 9 months (2,109 days;semi-major axis of 3.22 AU). Its orbit has aneccentricity of 0.09 and aninclination of 4° with respect to theecliptic.[3] The body'sobservation arc begins at theBergedorf Observatory on 30 September 1916, one week after its official discovery observation atHeidelberg.[1]
Any reference of thisminor planet's name to a person or occurrence is unknown.[2]
Among the many thousands ofnamed asteroids,Olivia is one of 120 planets for whichno official naming citation has been published. All of these asteroids have low numbers, the first one being164 Eva. The last asteroid with a name of unknown meaning is1514 Ricouxa. They were discovered between 1876 and the 1930s, predominantly by astronomersAuguste Charlois,Johann Palisa,Max Wolf andKarl Reinmuth.[11]
In theSDSS-based taxonomy,Olivia is a common, carbonaceousC-type asteroid, with a notably lowalbedo(see below).[10]
As of 2020, no rotationallightcurve ofOlivia has been obtained fromphotometric observations. The body'srotation period,pole and shape remain unknown.[3][5][9][12]
According to the surveys carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer (WISE), the Infrared Astronomical SatelliteIRAS, and the JapaneseAkari satellite,Olivia measures (30.418±0.082), (35.65±2.3) and (36.05±0.91) kilometers in diameter and its surface has a notably lowalbedo of (0.033±0.006), (0.0242±0.004) and (0.025±0.001), respectively.[6][7][8] Alternative mean-diameters published by the WISE team include (35.367±13.540 km) and (44.231±0.847 km) with corresponding albedos of (0.031±0.031) and (0.025±0.005).[5]
