Japetus-N00081090.jpgThe unusual shape of Japetus... (true colors, elab. Lunexit)53 visitePianeta o Pianetoide? Sfera o Sferoide?
Il problema sembra ozioso (e, forse, lo è davvero...), ma la curiosità è grande: come mai Giapeto ha un aspetto così "angolare" - notate il suo profilo - mentre (quasi) tutte le altre Lune Maggiori di Saturno sono delle sfere decisamente belle e lineari? Forse perchè Giapeto si è raffreddato (acquisendo la sua forma finale) molto più rapidamente rispetto a quanto non abbiano fatto gli altri corpi celesti che orbitano nello Spazio di Saturno.
O forse perchè su Giapeto è accaduto qualcosa di devastante. Un evento catastrofico il quale è stato capace, oltre che di renderlo...bicolore (metà di questo mondo, infatti, è color nero, mentre un'altra metà tende al bianco/marrone, con qualche accenno di rosa), anche di "deformarlo".
O forse si è trattato di una serie di eventi ricollegabili agli stress-mareali ai quali questo piccolo mondo (al pari di tutti gli altri mondi che orbitano intorno ai Giganti Gassosi) è stato ed è sottoposto?
Difficile (se non impossibile) dare una risposta sicura. Diciamo che, nel momento in cui saremo stati capaci di individuare ed analizzare tutte le possibili situazioni (e, quindi, oltre a quelle citate, anche 100 altre...), avremo compiuto un lavoro eccellente. Per il resto, noi riteniamo che, anche possedendo una Scienza Perfetta (che comunque non abbiamo...), ad alcune domande, con ogni probabilità, una risposta netta e finale non sarà MAI possibile darla.

Nota Lunexit: l'evidente sovraesposizione della falce illuminata di Giapeto ci induce a ritenere (ragionevolmente) che alcuni dei punti luminosi visibili nello spazio circostante la luna Saturniana non sìano i soliti image-artifacts, ma vere e proprie stelle (raramente visibili in frames che riprendono corpi molto luminosi - in questo caso, poi, oltre alla sovraesposizione, ci aiuta anche la bassissima albedo che caratterizza un'ampia porzione di Giapeto).MareKromium
