Earths Nearest Neighbor

Although the Moon looks round, it is slightly egg-shaped and is much smaller than Earth. It is a little more than one-fourth the size of Earth. The Moon does not have an atmosphere to protect it, so it can get as cold as -200°F at night or as hot as the boiling point of water during the dayl

While planets in the solar system orbit the Sun, moons travel around the planets. Our Moon orbits Earth 27.3 days, nearly a month.
