Tygge Brahe (latinizzato in Tycho Brahe<\/i>, 1546-1601) era un astronomo danese, noto principalmente per aver fornito a Keplero una serie di osservazioni estremamente accurate che permisero a quest’ultimo di enunciare le tre famose leggi sui moti planetari. Brahe \u00e8 stato uno dei pi\u00f9 grandi osservatori dell’era pre-telescopica, oltre ad essere un uomo piuttosto litigioso e difficile. Da giovane perse un pezzetto di naso in un duello con il cugino, prontamente sostituito con una protesi fatta di rame e cera, che Tygge ostentava con orgoglio. <\/p>\n

Tycho \u00e8 uno dei crateri pi\u00f9 importanti della Luna, non tanto per le sue dimensioni (raggiunge appena i 90 km) ma per l’albedo estremamente elevato tanto del cratere che della sua eccezionale raggiera. Le pareti alte e ben definite, insieme agli ejecta<\/i> otticamente immaturi collocano Tycho nel periodo Copernicano, riservato alle formazioni pi\u00f9 giovani del nostro satellite.<\/p>\n<\/p>\n

(ENG) Tygge Brahe (latinized <\/i>Tycho Brahe, 1546-1601) was a Danish astronomer, mainly known for providing Kepler with an extremely accurate sets of observations which allowed the latter to state his famous three laws about planetary motions. Brahe has been one of the greatest observers in the pre-telescopic era, aside from a quite quarrelsome and hard to deal with man. When he was young, he had a part of his nose cut in a duel with his cousin, promptly replaced with an artificial one made of copper and wax.

Tycho is one of the most prominent crater of the Moon, not just because its size (barely reaching 90 km) but for the extremely high albedo both of the crater and its exceptionally wide ray system. The high, well defined walls, and the optically immature rays concur in placing Tycho in the Copernican lunar period, reserved to the youngest features of our satellite. <\/i><\/p>\n<\/div><\/div><\/div><\/div><\/div>

I contrasti, in questa ripresa, appaiono piuttosto piatti a causa della fase lunare avanzata (82%). Si noti una lunga catena di craterini, che corre diagonalmente dalla parete occidentale del cratere. <\/p>\n
