The Moon 

The Moon has been an object of wonder and amazement for centuries. As the only natural satellite of Earth, it has been observed and visited numerous times through the recent space programs launched by different countries around the world.

It has a radius of 1,738 kilometers (1,080 miles) and is about 1/4 the size of Earth. It is easily visible by the naked eye and is strikingly detailed with modern telescopes. The surface is categorized into two types of terrain. The first type is a rough and bright type that is composed mainly of mountains and valleys. The second type is a darker type with smoother plains.

The Moon is tidally locked to Earth with its one face continuously facing Earth and never revealing its dark side. This is due to the position and how the two planetary bodies orbit each other.

The Moon's face is replete with numerous impact craters with several large and bright rayed craters. There is still much to learn about this natural satellite as in the future, as many more planned missions will be launched to rendezvous with our closest neighbor.
