Questions: 1. What was the phase of the moon after seven days? 2. How long does it take before a new moon becomes a full moon? 3. How long does it take for the moon to complete all of its phases?
first quarterMany people say this looks like a banana or the letter C. 7 days later the moon is 90 degrees away from the Sun and is half illuminated. This phase is called “first quarter” because it is about a quarter of the way around the Earth. Over the next 7 days the moon continues to be in a waxing state.
2.about 29.5 days
about 29.5 daysIt takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).
