1711 Sandrine


1711 Sandrine, provisional designation, is a stony Eoan asteroid from the outer region of the asteroid belt, approximately 23 kilometers in diameter.
This asteroid was discovered on 29 January 1935, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle. It was named after the grand-nice of astronomer Georges Roland.

Classification and orbit

Sandrine is a member of the Eos family, the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids. It orbits the Sun in the outer main-belt at a distance of 2.7–3.4 AU once every 5 years and 3 months. Its orbit has an eccentricity of 0.12 and an inclination of 11° with respect to the ecliptic. The body's observation arc begins with its official discovery observation. Its first observation at Heidelberg in 1909, when it was identified as, has been discarded.

Physical characteristics

In the Tholen classification, Sandrine is characterized as a common S-type asteroid.

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. It has an absolute magnitude of 11.01.

Lightcurves

As of 2017, Sandrines rotation period and shape remain unknown.

Naming

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. The official naming citation was published by the Minor Planet Center on 8 April 1982.
