1617 Alschmitt, provisional designation 1952 FB, is an assumed carbonaceous asteroid from in the outer parts of the main belt, approximately 30 kilometers in diameter. It was discovered on 20 March 1952, by French astronomer Louis Boyer at Algiers Observatory in Algeria, Northern Africa.
This C-type asteroid orbits the Sun at a distance of 2.8–3.6 AU once every 5 years and 9 months (2,090 days). Its orbit has an eccentricity of 0.13 and an inclination of 13° with respect to the ecliptic.Alschmitt was first identified as A906 DC at Heidelberg in 1906, extending the body's observation arc by 46 years prior to its official discovery observation.
Two rotational light-curve of Alschmitt obtained in 2003 and 2004, by René Roy and Laurent Bernasconi, gave a well-defined rotation period of 7.0613 and 7.062 hours with a brightness variation of 0.39 and 0.52 in magnitude, respectively (U=3/3). In October 2010, the Palomar Transient Factory derived a period of 7.0602 hours with an amplitude 0.49 magnitude (U=2).
