1683 Castafiore, provisional designation 1950 SL, is a carbonaceous asteroid from the outer region of the asteroid belt, about 21 kilometers in diameter. It was discovered by Belgian astronomer Sylvain Arend at Royal Observatory of Belgium in Uccle on 19 September 1950.[6]
The C-type asteroid orbits the Sun at a distance of 2.2–3.2 AU once every four and a half years (1,653 days). Its orbit shows an eccentricity of 0.18 and is tilted by 13 degrees to the plane of the ecliptic. It has a rotation period of 13.9 hours[lower-alpha 1] and an albedo in the range of 0.09–0.12, as measured by the WISE/NEOWISE mission.[4][5]
It is named after the fictional Adventures of Tintin character, Bianca Castafiore.[2] On the occasion of his seventy-fifth birthday, the father of the comic-strip character, Georges Remi, better known under his pseudonym Hergé, was honoured by the minor planet 1652 Hergé.[7]
