Donati is a lunar impact crater that is located in the rugged south-central highlands. It lies just to the northwest of the crater Faye, and the two outer rims are separated by a gap of less than 10 kilometers. To the north is the comparably sized Airy, and farther to the southeast is Playfair. Donati is 36 kilometers in diameter. (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.
