1048 Feodosia, provisional designation , is a carbonaceous
asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere.

from the middle region of the
asteroid belt, approximately 70 kilometers in diameter.
It was discovered on 29 November 1924, by German astronomer
Karl Reinmuth at
Heidelberg Observatory
Heidelberg (; Palatine German: ') is a city in the German state of Baden-Württemberg, situated on the river Neckar in south-west Germany. As of the 2016 census, its population was 159,914, of which roughly a quarter consisted of students.

in southwest Germany, and named for the Crimean city of
Feodosiya.
Classification and orbit
''Feodosia'' orbits the Sun in the
middle main-belt at a distance of 2.2–3.2
AU once every 4 years and 6 months (1,650 days). Its orbit has an
eccentricity of 0.18 and an
inclination of 16
° with respect to the
ecliptic.
The body's
observation arc begins at
Johannesburg, 3 years after its official discovery observation at Heidelberg.
On 22 November 2005, it
occulted
An occultation is an event that occurs when one object is hidden from the observer by another object that passes between them. The term is often used in astronomy, but can also refer to any situation in which an object in the foreground blocks ...

Physical characteristics
The dark C-type asteroid is classified as a XC and Ch intermediary type in the Tholen
Tholen () is a 25,000 people municipality in the southwest of the Netherlands. The municipality of Tholen takes its name from the town of Tholen, which is the largest population center in the municipality.
The municipality consists of two peninsu ...
and SMASS taxonomy, respectively.
Photometry
In March 1985, a rotational lightcurve of ''Feodosia'' was obtained by European astronomer at ESO's La Silla Observatory in Chile, using the Bochum 0.61-metre Telescope
La Silla Observatory is an astronomical observatory in Chile with three telescopes built and operated by the European Southern Observatory (ESO). Several other telescopes are located at the site and are partly maintained by ESO. The observatory is ...
during three nights. It gave a rotation period
The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) may refer to its sidereal rotation period, i.e. the time that the object takes to complete a single revolution around its axis of rotation relative to the ...
of 10.46 hours with a brightness variation of 0.14 magnitude ().
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 54.98 and 85.14 kilometers in diameter, and its surface has an albedo between 0.031 and 0.06.
Naming
This 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
Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems using a Kepler orbit. There are many different ways to mathematically describe the same ...
