Hovnatanian

Feature type	Impact crater
Location	Tolstoj quadrangle, Mercury
Coordinates	7°41′S 187°17′W / 7.68°S 187.29°W / -7.68; -187.29
Diameter	34 km (21 mi)
Eponym	Hakob Hovnatanyan

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 (similar to Messier crater on the Moon), the Hovnatanian impactor was travelling either north-to-south or south-to-north prior to hitting Mercury's surface.^[1] Hovnatanian lies to the west of Tir Planitia.

The crater was named in 2008 for Hakob Hovnatanyan, a 19th-century Armenian artist.^[2]
