Prepare yourself for a sight tonight — not to mention some wild behavior, if the legends are true. The biggest full moon in 15 years is set to grace the Northern Hemisphere tonight. Because the moon orbits along an egg-shaped ellipse, not a circle, its distance from us changes. Today, the moon is approaching its nearest point to Earth, so it should look about 14 percent bigger and 30 percent brighter than this year's other full moons, according to NASA.
