Sayat-Nova is an impact crater on the planet Mercury. It is named for the Armenian/Georgian song writer Aruthin Sayadian Sayat-Nova. Its name was approved by the International Astronomical Union in 1979. The crater was first imaged by Mariner 10 in 1974.
Sayat-Nova is located on the southern rim of the larger Beethoven basin. A scarp cutting east-west across Sayat-Nova corresponds with the original rim of Beethoven.Preusker, F., J. Oberst, D. T.
