I travel around the earth in a path called an ORBIT. Click on me to learn more about my different PHASES.

The first humans to walk on the moon were Buzz Aldrin and Neil Armstrong. They were a part of the Apollo 11 spaceflight which landed on July 20, 1969.

The LUNAR CYCLE, the time it takes for the moon to complete all 8 phases, is 29.5 days long.

Earth spins on an AXIS, while the sun stays in the same place. Click here to learn more!
