The full moon of February, known as the Snow Moon, will reach peak illumination in the eastern U.S. at 8:53 a.m. EST (1353 GMT) on Feb. 12, three days after it occults Mars.
The full moon occurs when the moon is directly opposite the sun from Earth's perspective. Most of the time, it is fully illuminated by sunlight. Occasionally, the moon's orbit carries it into Earth's shadow, causing a lunar eclipse. However, February's full moon will bypass Earth's shadow because the moon's orbit is tilted about five degrees relative to Earth's orbital plane, preventing perfect alignment between the sun, Earth, and moon.
