This asteroid was discovered on 29 January 1935, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle.[5] It was named after the grand-niece of astronomer Georges Roland.[2]
Classification and orbit
Sandrine is a member of the Eos family (606), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids.[3][6]:â23â It orbits the Sun in the outer main-belt at a distance of 2.7â3.4 AU once every 5 years and 3 months (1,910 days). Its orbit has an eccentricity of 0.12 and an inclination of 11° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation. Its first observation at Heidelberg in 1909, when it was identified as A909 DJ, has been discarded.[5]
Physical characteristics
In the Tholen classification, Sandrine is characterized as a common S-type asteroid.[1]
Diameter and albedo
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Sandrine measures 22.93 kilometers in diameter, and its surface has an albedo of 0.133.[4] It has an absolute magnitude of 11.01.[1]
Lightcurves
As of 2017, Sandrine's rotation period and shape remain unknown.[1]
Naming
This minor planet was named after Sandrine, a grand-niece of Georges Roland, astronomer at Uccle and co-discoverer of Comet ArendâRoland. Delporte also named 1707 Chantal and 1848 Delvaux after family members of his collaborator.[2] The official naming citation was published by the Minor Planet Center on 8 April 1982 (M.P.C. 6832).[7]
