A lunar phase is a reference to the illuminated portion of the moon as it looks to an observer on Earth. There are nine lunar phases, and the phases vary cyclically as the Moon orbits the Earth. The portion of the moon that is visible to the observer varies from 100% (which is usually referred to as the full moon) to 0% (which is usually referred to as the new moon). It takes about 27. 32 calendar days (or about 1 month) for the moon to complete its orbit around the Earth! This cool mug shows all of the stages of the moon according to the calendar year of 2008. Want to see when the moon is going to be full or new during August? Just take a quick look at the side of your mug when you’re drinking coffee tomorrow morning!! The sleek lunar phases chart is imprinted in silver and set on a beautiful cobalt blue mug. Cool gift for Father’s Day! Or get it for your favorite co-worker for a stand-out mug in the office!!
