Tags: Crater.
Isaev is a lunar crater on the far side of the Moon. It is entirely contained within the much larger walled plain Gagarin and lies in the northwestern part of Gagarin’s interior floor. The northwestern outer rim of Isaev is attached to the inner rim of Gagarin.Although younger than Gagarin in which it lies this is still an eroded crater formation. The southern rim is broken through by the smaller satellite crater Isaev N. Tiny craterlets lie along the rim and inner walls of Isaev.
