Earths Moon

Earth's closest neighbor Is Its moon. The Moon Is about 240,000 miles from Earth. The Moon orbits Earth just as Earth orbits the Sun. Just as the Sun's gravity keeps Earth from spinning off into space. Earth's gravity keeps the Moon in place. The Moon is roughly a quarter the diameter of Earth. It would take about 81 moons to make up the same weight as Earth. The Moon's gravity is very weak, one-sixth as great as the Earth's gravity. The Moon's gravity is too weak to hold an atmosphere. The Moon Is a stark, arid place, hot in the day and very cold at night. The surface of the Moon is a desert of rock and dust. The light that we see from the Moon is reflected sunlight. As the Moon orbits Earth, we see varying parts of the Moon lit up by sunlight. The changing appearance of the Moon is called its cycle of phases. The Moon spins on an axis, but It always keeps the same face to Earth because it rotates and spins at the same rate. Astronauts learned from their trip to the Moon that people could live there if they brought their own water, air, and food.
