Poyasnenie: Kopernik odin iz samyh vazhnyh kraterov na Lune. Vy sprosite kak ya mogu nazvat' chto-libo na Lune "naibolee vazhnym"? Pozvol'te mne izmenit' pervoe predlozhenie i Vy veroyatno soglasites': Kopernik samyi vazhnyi krater na Lune iz-za togo, chemu on nas nauchil. Vot tri uroka, kotorye on nam prepodnes. Pervyi urok: Pochti stokilometrovyi (v poperechnike on 93 km) Kopernik yavlyaetsya obrazcovym slozhnym udarnym kraterom. Dlya kraterov s poperechnikom bolee 15 kilometrov u Kopernika prisutstvuyut vse tri tipa obrazovanii: vnutrennie steny s rezkimi obryvami i terrasy, bol'shie otnositel'no ploskie ploshadki i central'nye piki. Vtoroi urok: Evgenii Shumeiker ispol'zoval krater Kopernik v kachestve tipichnogo primera v ego analiticheskoi rabote, posvyashennoi fizike formirovaniya udarnyh kraterov, ob'yasnyayushei proishozhdenie obrazovanii, perechislennyh vyshe, a takzhe vtorichnye kratery i luchi. Tretii urok: Kopernik okazalsya bolee slozhen, chem my schitali. Ya eto obnaruzhil, kogda sravnival ego s drugimi bolee pozdnimi kraterami so slozhnoi strukturoi. Tak Kopernik okazalsya slishkom melkii (poryadka 700 metrov), a central'nye piki dovol'no nizkimi (poryadka odnogo kilometra). Takim obrazom Kopernik zapolnen v predelah ot 0.7 do 1.0 km neizvestnym materialom. Vryad li eto mozhno ob'yasnit' oplavleniem (takoi sloi dolzhen byt' poryadka chetverti kilometra), vprochem takzhe kak i drugoi variant - potokami lavy. Poslednii variant voobshe ne lyubyat, potomu chto iz etogo sleduet, chto Luna byla sravnitel'no nedavno goryachei - poryadka 1 milliarda let nazad. Odnako dlya togo, chtoby voshishat'sya etim prevoshodnym snimkom, sdelannym Bruno Daversinom s ispol'zovaniem 24-h dyuimovogo teleskopa observatorii Lyudiver (Ludiver), vovse ne nuzhno znat' iz chego sostoit material na dne kratera - eto mozhet byt' lava, ili mozhet on obrazovalsya v rezul'tate oplavleniya v rezul'tate udarnogo vozdeistviya, a mozhet eto imenno sluchainye otkloneniya ot srednih znachenii dlya analogichnyh kraterov.
