945 Barcelona is aminor planet orbiting theSun in theAsteroid belt. It was discovered 3 February 1921 fromBarcelona by theCatalanastronomerJosep Comas i Solà (1868–1937) and named for the city ofBarcelona (Spain), the birthplace of the discoverer. It has an estimated diameter of 25.5 km.
This object is the namesake of aBarcelona family of approximately 300 stony asteroids that share similar spectral properties andorbital elements; hence they may have arisen from the same collisional event. All members have a relatively highorbital inclination.[2]
