Kostinsky is a lunarimpact crater on the far side of the Moon. It is nearly attached to the northeastern outer rim of the crater Guyot. About one crater diameter to the southeast is Ostwald, and farther to the north is Olcott.
The rim of Kostinsky is eroded, and along the southeast has been nearly worn away. The rim has an outward bulge along the northeastern side. There is a small crater intruding into the eastern rim. The interior floor has some irregularities in the southwest quadrant, and along the edge of the bulging section to the northeast.
The crater was named after the Russian astronomer Sergey Kostinsky in 1970.[1] Prior to that, this crater was known as Crater 210.[2]
