  • "Lunar 100" è un elenco delle cento caratteristiche più interessanti da osservare sulla Luna. L'elenco venne descritto per la prima volta da Charles A. Wood nell'articolo pubblicato sulla rivista Sky & Telescope (Aprile 2004) con l'intento di fornire agli appassionati di astronomia un elenco riguardante il nostro satellite naturale, simile al catalogo di Messier per gli oggetti deepsky. Le strutture lunari citate comprendono le varie tipologie di formazioni geologiche visibili sulla superficie della Luna e vengono presentate in ordine crescente di difficoltà di osservazione.
