    1675 Simonida, provisional designation 1938 FB, is a stony asteroid from the inner regions of the asteroid belt, about 11 kilometers in diameter. It was discovered by Serbian astronomer Milorad Protić at Belgrade Astronomical Observatory on 20 March 1938.[9] On the same night, the body was independently discovered by Belgian astronomer Fernand Rigaux at the Royal Observatory of Belgium in Uccle.[2]

    The asteroid is a member of the Flora family, a large group of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,219 days). Its orbit shows an eccentricity of 0.12 and is tilted by 7 degrees to the plane of the ecliptic. Its albedo of 0.248 was measured by the Infrared Astronomical Satellite, IRAS, and by the Japanese astronomy satellite, Akari.[4][5] The S-type asteroid rotates around its axis every 5.3 hours.[6][7][8]

    It was named after Byzantine princess and queen consort Simonida, the wife of medieval Serbian king Stefan Milutin and symbol of beauty in former Yugoslavia.[2]
