Lunar 100
Il Lunar 100 è un elenco delle 100 formazioni più interessanti da osservare sulla Luna. L’elenco è stato descritto da Charles A. Wood nell’articolo The Lunar 100 nel numero di aprile 2004 della rivista Sky and Telescope.
Gli oggetti elencati includono crateri, mari, montagne e altre caratteristiche e sono disposti in ordine crescente di difficoltà di osservazione.
