Upea kuva! Nuo isot kolme kraatteria ovat kaikki enemmän tai vähemmän kuusikulmaisia. Hieno yksityiskohta on esim. Catena Davy, n. 50km pitkä, pienistä kraattereista koostuva ketju.

Kiitos Jari! Enpäs ole ennen huomannutkaan tuota kuusikulmaisuutta. Ja kun tarkemmin katsoo, niin aika moni noista pienemmistäkin on huomattavan kuusikulmainen.
