0 The Moon is a ball of grey rock about a quarter as wide as the Earth, circling us about 384,000 kilometres away, the width of about 30 Earths in a row. 1 It spins exactly once each time it goes round us, like a dancer who keeps facing her partner, so we always see the same face. 2 The dark patches people call seas are plains of old hardened lava, and the rest is scarred with craters left by rocks from space. 3 There is almost no air, so on the Moon the sky is black even by day, there is no wind and no sound, and footprints can last for millions of years. 4 Gravity there is only one sixth of ours: a 30-kilogram child would feel as light as 5 kilograms and could bound like a kangaroo. 5 The Moon is about a quarter of the Earth's width and orbits about 384,000 kilometres away, a distance of about 30 Earths lined up. 6 The Moon always shows the same face to the Earth because it spins once in exactly the time it takes to orbit, about 27 days. 7 The far side of the Moon is not dark; it gets just as much sunlight as the near side, we simply never see it from the Earth. 8 The dark patches on the Moon are called maria, Latin for seas, but they are plains of ancient hardened lava, not water. 9 The Moon is covered in craters, some hundreds of kilometres wide, made by asteroids and comets hitting it. 10 Gravity on the Moon is about one sixth of the Earth's, so a 30-kilogram child would feel as light as 5 kilograms. 11 The Moon has almost no atmosphere, so there is no sound, no wind and the sky is black even in daytime. 12 Twelve astronauts walked on the Moon in six Apollo landings between 1969 and 1972, starting with Neil Armstrong and Buzz Aldrin. 13 In April 2026 the Artemis II mission was reported to have flown four astronauts around the Moon, the first crew to go there since 1972; they did not land. 14 Water ice exists in permanently shadowed craters near the Moon's poles. 15 The Moon is slowly drifting away from the Earth by about 3.8 centimetres a year. 16 The Moon makes no light of its own; it shines by reflecting sunlight. ← previous The Earth as a planetnext → Phases, eclipses and tides↑ back to Space This page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/space/6-the-moon/
