3703 Volkonskaya, provisional designation 1978 PU3, is a Vestian asteroid and asynchronous binary system from the inner regions of the asteroid belt, approximately 4 kilometers (2.5 miles) in diameter. It was discovered on 9 August 1978, by Soviet astronomers Lyudmila Chernykh and Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula. It was named by the discoverers after the Russian princess Mariya Volkonskaya.[1] The V-type asteroid has a rotation period of 3.2 hours. The discovery of its 1.4-kilometer minor-planet moon was announced in December 2005.[5]
