1048 Feodosia, provisional designation 1924 TP, is a large, carbonaceous asteroid from the outer region of the asteroid belt, about 70 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany, on 29 November 1924.[9]

The dark C-type asteroid, classified as a XC and Ch-subtype on the Tholen and SMASS taxonomic scheme, respectively, orbits the Sun at a distance of 2.2–3.2 AU once every 4 years and 6 months (1,648 days). Its orbit is tilted by 16 degrees to the plane of the ecliptic and shows an eccentricity of 0.18. It has a rotation period of 10.5 hours[7] and an albedo varying between 0.04 and 0.06, according to the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the U.S. Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission.[4][5][6] On November 22, 2005, the asteroid occulted the star TYC 1236-138 as seen from Earth.[10]

The minor planet was named for the city Feodosiya on the Crimean peninsula. The named was proposed by I. Putilin, who computed the body's orbital elements.[2]
