Andronov lies on the south-western rim of Gagarin -- a 265 km-wide diameter crater of the pre-Nectarian age (~ 4.6 - 3.92 bn years). Several craters in Gagarin's floor are similar in size to Andronov, however, while its bowl shaped, sharp-ish rim looks relatively fresh to most, it too shows signs of impact history -- having one or two smaller craters on its rim. The large, right-most crater in the Apollo image above is Raspletin, which lies on Gagarin's south-eastern rim -- itself lying very close to the outer ring of the South Pole Aitken Basin.
