Sisakyan (crater)
Sisakyan is a lunar crater that is located on the Moon's far side, beyond the northeastern rim. It lies to the east of the huge walled plain Harkhebi, and north of the crater Sumner and the Catena Sumner crater chain.
This is a heavily eroded crater formation with a rugged outer rim and an uneven interior floor. There are smaller craters attached to the exterior rim along the northwest, northeast, and southeast.
