    1263 Varsavia, provisional designation 1933 FF, is a metallic–carbonaceous, notably tilted asteroid from the middle region of the asteroid belt, about 49 kilometers in diameter. It was discovered by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle, on 23 March 1933.[13]

    The X-type asteroid is classified as a Xc-type in the SMASS taxonomy, a transitional type to the dark C-type asteroids. It orbits the Sun at a distance of 2.2–3.2 AU once every 4 years and 4 months (1,590 days). Its orbit shows an eccentricity of 0.19 and is significantly inclined by 29 degrees to the plane of the ecliptic. It has a rotation period of 7.2 hours[9] and an albedo of 0.040–0.08, based on the space-spaced observations carried out by IRAS, Akari, and WISE/NEOWISE.[4][7][8]

    The minor planet was named after the Latin name of the city of Warsaw, capital of Poland. The naming citation includes a note of thanks for the support given by the city's observatory.[2]
