“The moon will appear large because it’s reaching its ’perigree,’ the closest approach to earth in its orbit. According to NASA, perigree moons are 14% bigger and 30% brighter than moons on the ‘apogee’ side of the moon’s orbit, when it is farthest away from earth. What’s special about Saturday’s perigree moon is that it’s almost coinciding with a full moon, a relatively rare occurrence. Some refer to this coincidence as a ‘supermoon.’”
Some believe the super moon is associated with natural disasters, but Capital Weather Gang says there is little scientific evidence to back up that view.
