1711 Sandrine, provisional designation 1935 BB, is a stony asteroid from the outer region of the asteroid belt, approximately 23 kilometers in diameter. It was discovered on 29 January 1935, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle.
The S-type asteroid orbits the Sun at a distance of 2.7–3.4 AU once every 5 years and 3 months (1,910 days). Its orbit has an eccentricity of 0.11 and an inclination of 11° with respect to the ecliptic. Sandrine's observation arc begins with its official discovery observation. Its first unused identification as A909 DJ was made at Heidelberg in 1909.
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. It has an absolute magnitude of 11.01. As of 2017, Sandrine's rotation period and shape remain unknown.
This minor planet was named after Sandrine, a grand-niece of Georges Roland, astronomer at Uccle and co-discoverer of Comet Arend–Roland. Delporte also named 1707 Chantal and 1848 Delvaux after family members of his collaborator. Naming citation was published on 8 April 1982 (M.P.C. 6832).
