The Moon -- by Wysper and Mitch

Wysper and Mitch worked on this blog. Can you tell what part Wysper wrote?

The Moon is a natural satellite of Earth. That means that it revolves around the earth. It takes about 28 days for the moon to circle the earth. The moon also spins on its axis. It spins around once in every 28 days. Therefore, the same side of the moon always faces the earth.  The other side of the moon, which we cannot see from earth is sometimes called “the dark side of the moon.”

Actually, just like the planets, one half of the moon faces the sun, and the other faces away. Because the moon spins, it is not always the same side of the moon which is dark. And sometimes, the side with no sunlight on it faces the earth.

As it spins, more and more of the side that is illuminated by the sun faces us. We say that moon is waxing. At first it is a tiny sliver, but it grows to be a crescent, and then a full moon. Then it starts to get smaller, and we say it is waning.  The whole process is takes 28 days, and this is what we call a month on the lunar calendar.

 The gravity of the moon affects the tides. Wysper and Sponge Bob went to Bikini Bottom. The first human landing on the Moon was on 20 July 1969. During the Apollo missions of 1969-1972, 12 American astronauts walked on the Moon and used a Lunar Roving Vehicle to travel on the surface. Wysper and Sponge Bob were jelly-fishing on the moon.
