2747 Český Krumlov (Czech: [ˈtʃɛskiː ˈkrʊmlof]), provisional designation 1980 DW, is a carbonaceous asteroid and slow rotator from the outer regions of the asteroid belt, approximately 33 kilometers in diameter. It was discovered by Czech astronomer Antonín Mrkos at Kleť Observatory on 19 February 1980.[1]
The asteroid belongs to the Hygiea family and is dark colored (hence probably a carbonaceous C-type).
It is named after the historic Czech town of Český Krumlov, near to the location of the discovering Kleť Observatory.[2]
