30564 Olomouc (IPA: [ˈolomoʊ̯ts]) is a main belt asteroid. It was discovered by Petr Pravec on July 28, 2001 in Ondřejov and was named after Olomouc, a city in central Moravia, the Czech Republic, where the discoverer lived.

The citation accompanying the suggestion of the name and published in the Minor Planet Circular on 6 January 2003 said: "The city of Olomouc is the center of the Haná region in the heart of Moravia. The seat of Catholic bishops since 1063 and Moravian primates since 1777, it has been home to a university since 1573, now called Palacký University."

[edit] Physical characteristics

On the basis of its absolute magnitude in the visible light spectrum and supposed albedo (which usually varies from 0.05 to 0.25 for the main belt asteroids) the diameter of the asteroid 30564 Olomouc can be estimated from 2.6 to 5.9 km. Since astronomers do not have the spectral data on the asteroid, neither its chemical nor mineralogical composition is known.
