Gagarin is a large lunar impact crater that is located in the southern hemisphere on the far side of the Moon.

[citation needed] The crater is named after Yuri Gagarin, the cosmonaut who was the first human in space and the first to orbit the Earth.

[1] The six craters falling within the perimeter of Gagarin have also been named after pioneers of Russian aviation and astronautics, including Isaev, Grave, Balandin, Raspletin, Kosberg, and Andronov.

[citation needed] Gagarin has been heavily eroded by a long history of crater impacts.

[citation needed] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Gagarin.
