Over many years, the molten material slowly hardened resulting in the lunar planet. It has many similarities with Earth, including a crust, core, and mantle. The Moon also has an atmosphere which is called the exosphere. Unlike that of the Earth’s atmosphere, the moon’s exosphere is a weak and unstable barrier. Therefore the moon is vulnerable to asteroids, and other space junk. It’s gravity is ⅙ of what it is on Earth, which means you would be able to float if you were not weighted down. When the Moon is in direct contact with the sun, the temperature on its surface heats up to 127 degrees Celsius. For the moon surface not facing earth, temperatures can drop to -173 degrees
