1083 Salvia (prov. designation:1928 BC) is a stonybackground asteroid from the inner regions of theasteroid belt. It was discovered on 26 January 1928, by astronomerKarl Reinmuth at theHeidelberg Observatory in southwest Germany.[1] The assumedS-type asteroid has arotation period of 4.2 hours and measures approximately 10 kilometers (6.2 miles) in diameter. It was named after the flowering plantSalvia (sage).[3]
Located in the region of theFlora family,[9]Salvia is a non-family asteroid of the main belt'sbackground population when applying thehierarchical clustering method to itsproper orbital elements.[5][6] It orbits the Sun in theinner asteroid belt at a distance of 1.9–2.8 AU once every 3 years and 7 months (1,298 days;semi-major axis of 2.33 AU). Its orbit has aneccentricity of 0.18 and aninclination of 5° with respect to theecliptic.[4] The asteroid was first observed asA910 AA atHeidelberg Observatory on 7 January 1910, where the body'sobservation arc begins 18 years later, with its official discovery observation on 26 January 1928.[1]
Thisminor planet was named after the flowering plantSalvia (sage), a genus of herbs or shrubs that belong to themint family. The official naming citation was mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 102).[3]
Due to his many discoveries,Karl Reinmuth submitted a large list of 66 newly named asteroids in the early 1930s. The list covered his discoveries with numbers between(1009) and(1200). This list also contained a sequence of 28 asteroids, starting with1054 Forsytia, that were all named after plants, in particularflowering plants(also see list of minor planets named after animals and plants).[12]
Salvia is an assumed stonyS-type asteroid, which corresponds to its observedalbedo(see below).[9]
In March 1992, a rotationallightcurve ofSalvia was obtained from photometric observations by Polish astronomerWiesław Wiśniewski. Lightcurve analysis gave a well-definedrotation period of 4.23 hours with a brightness amplitude of 0.61magnitude (U=3).[11] A 2016-published lightcurve, using modeled photometric data from the Lowell Photometric Database, gave a concurring period of4.281429±0.000001 hours, as well as twospin axis of (165.0°, −59.0°) and (358.0°, −58.0°) inecliptic coordinates (λ, β).[13]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer (WISE),Salvia measures between 8.927 and 10.283 kilometers in diameter and its surface has analbedo between 0.2103 and 0.2184.[7][8][10] TheCollaborative Asteroid Lightcurve Link adoptsPetr Pravec's revised WISE data, that is an albedo of 0.2103 and a diameter of 10.28 kilometers based on anabsolute magnitude of 12.25.[9]
