Tambi\u00e9n giraba mucho m\u00e1s deprisa. Poco a poco fue perdiendo velocidad y hoy la Luna completa una vuelta cada 27 d\u00edas, el mismo tiempo que tarda en viajar una vez alrededor de la Tierra. Esto significa que siempre vemos la misma cara de la Luna; la cara m\u00e1s lejana permanece siempre oculta a nuestra vista.<\/p>\n<\/div>\n<p>La Luna no tiene luz propia. Brilla al reflejar la luz del Sol. Al igual que la Tierra, la mitad de la Luna est\u00e1 iluminada por el Sol y la otra mitad est\u00e1 en la oscuridad (la noche). A veces vemos toda la cara diurna; a esto se le conoce como \u2018luna llena\u2019.<\/p>\n<p>A veces solo vemos una delgada franja curva de luz, llamada \u2018media luna\u2019. Otras veces no podemos ver la Luna en absoluto, porque estamos mirando su cara oculta. Esto es lo que se conoce como \u2018luna nueva\u2019.<\/p>\n<p>Desde tiempos inmemoriales, la gente ha observado c\u00f3mo la Luna parece cambiar de forma, pasando de una delgada media luna a la luna llena y viceversa. Estas \u2018fases\u2019 se deben a que la Luna da una vuelta alrededor de la Tierra cada 29 d\u00edas y medio. Este \u2018mes\u2019 se ha utilizado para medir el tiempo en todo el mundo desde hace miles de a\u00f1os.<\/p>","protected":false},"excerpt":{"rendered":"<p>Millions of years ago, the Moon was much closer and bigger in the sky.
