"He made an instrument to know If the moon shine at full or no; That would, as soon as eer she shone straight, Whether twere day or night demonstrate; Tell what her dameter to an inch is, And prove that shes not made of green cheese."
"How like a queen comes forth the lonely Moon From the slow opening curtains of the clouds Walking in beauty to her midnight throne!"

The Moon is the only natural satellite of Earth. It orbits around Earth at an average distance of 384,399 kilometres (238,854 mi), a distance roughly 30 times the width of Earth. It completes an orbit in relation to Earth and the Sun (synodically) every 29.5 days. The Moon and Earth are bound by gravitational attraction, which is stronger on the sides facing each other. The resulting tidal forces

"My dream would be to fly to the moon and build permanent structures, using the raw materials available there. For instance, regolith, or moon dust, could be used to make a form of concrete. Using 3-D printers, we could build all kinds of things with that moon concrete -- houses, streets and observatories, for example."
"The way Gaylord Perry swings a bat, he stands about as much chance of hitting a home run as ... oh ... as a man does of walking on the moon. Well, Perry and astronauts Neil Armstrong and Edwin Aldrin made it together Sunday. The San Francisco right-hander tagged his first career homer and pitched the Giants to a 7–3 victory over Los Angeles, tightening up the National Leagues West Division while the astronauts took a moon stroll that tightened up the universe."
"* * now glowd the firmament With living sapphires; Hesperus, that led The starry host rode brightest, till the Moon, Rising in clouded majesty, at length, Apparent queen, unveild her peerless light, And oer the dark her silver mantle threw."
"The moon, obviously, has its advantages [over Mars when considering future human spaceflight missions]. It is several orders of magnitude closer to Earth, which makes it a superb training ground for missions to Mars. Decades from now, when the first astronauts headed to Mars finish firing their rocket engines, their ship will be on an inevitable course that will require months, if not years, to return to Earth, and they had better be prepared for every contingency. The moon is only a few days from our home planet. As every test pilot knows, you should always use a buildup approach when developing new aircraft. In the same vein, our future astronauts will be well served to use the ISS and moon as test beds for the first Mars missions."
"Now Cynthia, named fair regent of the night."
