The last full moon of 2012 happens on Friday, Dec. 28 at 5:21 a.m. EST. The full moon occurs when the sun, the Earth and the moon line up in that order. The Sun’s light hits the side of the moon that faces the Earth, which it makes it look like a bright round disc in the sky.
The December full moon is called the oak moon as a testament to the season in which it appears (the October full moon is referred to as the harvest moon and the June full moon is known as the flower moon, for example).
