1711 Sandrine, provisional designation1935 BB, is a stony Eoanasteroid from the outer region of theasteroid belt, approximately 23 kilometers in diameter.
This asteroid was discovered on 29 January 1935, by Belgian astronomerEugène Delporte at theRoyal Observatory of Belgium in Uccle.[5] It was named after the grand-niece of astronomerGeorges Roland.[2]
Sandrine is a member of theEos family (606), the largestasteroid family in theouter main belt consisting of nearly 10,000 asteroids.[3][6]: 23 It orbits the Sun in theouter main-belt at a distance of 2.7–3.4 AU once every 5 years and 3 months (1,910 days). Its orbit has aneccentricity of 0.12 and aninclination of 11° with respect to theecliptic.[1] The body'sobservation arc begins with its official discovery observation. Its first observation atHeidelberg in 1909, when it was identified asA909 DJ, has been discarded.[5]
In theTholen classification,Sandrine is characterized as a commonS-type asteroid.[1]
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Sandrine measures 22.93 kilometers in diameter, and its surface has analbedo of 0.133.[4] It has anabsolute magnitude of 11.01.[1]
As of 2017,Sandrine'srotation period and shape remain unknown.[1]
Thisminor planet was named after Sandrine, a grand-niece of Georges Roland, astronomer at Uccle and co-discoverer ofComet Arend–Roland. Delporte also named1707 Chantal and1848 Delvaux after family members of his collaborator.[2] The official naming citation was published by theMinor Planet Center on 8 April 1982 (M.P.C. 6832).[7]
