Named after Nikolay Egorovich Zhukovskiy - Russian physicist (1847-1921).
Zhukovskiy is a lunar impact crater that lies on the far side. It forms a pair with Lebedinskiy, which is attached to the eastern rim. There are no other named craters of note in the immediate vicinity, although the immense walled plain Korolev lies farther to the southeast. The rim has become somewhat eroded, particularly at the northern and southern extremes. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
