7. The Moon Orbits Earth Regularly
Even though it doesn’t seem so from where we stand, the Moon actually takes a full 27.3 days (also called a sidereal month) to complete one complete revolution around the Earth. The constant movement of the Earth as well makes it tougher for the Moon to complete its revolution earlier.
This also means that the Moon has to travel at slightly more than 360 degrees to get to the next phase. In a synodic month or a lunar month, the moon takes around 29.5 days to complete one revolution around the Earth.
