Hovnatanian is a crater on Mercury. Its “butterfly” pattern of ejecta rays were created by an impact at an even lower angle than that which formed neighboring Qi Baishi crater. From the "butterfly" pattern of rays, the Hovnatanian impactor was travelling either north-to-south or south-to-north prior to hitting Mercury's surface.
The Hovnatanian family (, Hovnat'anyanner) was a prominent Armenian family of painters. They include five generations from 17th to 19th centuries. Hovnatanians are originally from the village of Shorot, Yernjak district in Nakhichevan (now Şurud village in Julfa Rayon, Nakhchivan, Azerbaijan).
They were based on Nakhichevan, Yerevan, Tbilisi, Ejmiatsin, Saint Petersburg and Persia. Most of their works are dedicated to Christianity like other works of their era.
