2. Our moonA moon is a satellite that goes around a planet. Someplanets, like Mercury, do not have a moon. Some planets,like Jupiter, have many moons. Earth has one moon.
3. Our moonThe moon is our nearest neighbor in space. It is smaller thanthe Earth. It is much smaller than the sun. It is much closer tothe earth than the sun is. The moon is about 239,000 milesaway from Earth. The sun is 93 million miles away!
4. Our moonThe moon goes around, or orbits, the Earth one time amonth (about every 29 days). The moon looks different to usas it orbits the Earth. It seems to change its shape ondifferent nights. This is called the moons phases. The moonsphase depends on its position and the position of the sun.The moon goes through eight different phases each month.
5. Our moonHave you ever seen the moon in the daytime? That isbecause of its position, too. When the moon is in the "full"phase, it rises at about sunset and sets at about sunrise. Thenwe see the moon when we dont see the sun. When themoon is in the "new" moon phase, we dont see the moon atall! It rises at about sunrise and sets at sunset. Its position is soclose to the sun that we cant see the moon.
6. Our moonThe moon does not make light. When we see "moonlight,"we are actually seeing sunlight that is reflecting off themoon. The moon acts like a giant mirror. The sun shines onthe moon, and the light bounces off or is reflected back tous on Earth.
7. Our moonThere have been several astronauts who have walked onthe moon. The first was Neil Armstrong who walked on themoon on July 20, 1969. There is no air or water on the moon.It is dry, dusty, and lifeless. Because there is no air, there is noweather, either. Astronauts who visit the moon today can stillsee Neil Armstrongs footprints in the dust. There has been nowind or rain to make the footprints go away. Whenastronauts go to the moon, they must take their ownair, food, and water.
8. Our moonThere are tall mountains and flat, dusty plains. There aremany big holes called craters. Craters are made whenspace rocks hit the moon. During the day when the sun isshining on it, the moon is very hot. It is hotter than boilingwater! During the night without the light from the sun, themoon gets very cold. This is because there is no air to holdthe suns heat.
