CHE SIGNIFICA LIGHT YEAR IN INGLESE
Anno luce
Un anno chiaro o chiaro di luce, a volte scritto, è un'unità di lunghezza utilizzata in astronomia, anche se a volte si sbaglia per un'unità di tempo. È uguale a poco meno di 10 trilioni di chilometri. Come definito dall'Unione Astronomica Internazionale, un anno luce è la distanza che la luce viaggia in vuoto in un anno di Giuliano. L'anno luce è più spesso usato quando esprime distanze a stelle e altre distanze su una scala galattica, in particolare nelle pubblicazioni scientifiche non specializzate e popolari. L'unità usata di astrometria professionale è il parsec.
