2047 Smetana (1971 UA1) is an inner main-belt asteroid discovered on October 26, 1971 by Luboš Kohoutek at Bergedorf Observatory, Germany. It is a member of the Hungaria family.[1][3]
Photometric observations of this asteroid collected during 2006 show a rotation period of 2.4969 ± 0.0004 hours with a brightness variation of 0.12 ± 0.02 magnitude. However, the short period may instead indicate it is a binary asteroid.[3]
The asteroid is named for the Czech national composer Bedřich Smetana (1824–1884), best known for the opera The Bartered Bride, the cycle of six symphonic poems My homeland and the string quartet From my life.[2]
