Eponym Puńsk, Poland

Púnsk Crater is an impact crater in the Oxia Palus quadrangle of Mars, located at 20.8° N and 41.2° W. It is 11.6 km in diameter and was named after Puńsk, Poland.[1] Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak.[2] The peak is caused by a rebound of the crater floor following the impact.[3]
