7 Things to know: Supermoon

June 22, 2013 1:57:23 PM PDT
A "supermoon" rises this weekend.

1) The biggest and brightest full moon of the year graces the sky early Sunday as our celestial neighbor swings closer to Earth than usual.

2) The supermoon will appear 14 percent larger than normal, but sky watchers won't be able to notice the difference with the naked eye.

3) The supermoon is actually an optical illusion. The moon looms larger on the horizon next to trees and buildings.

4) The moon will come within 222,000 miles of Earth and turn full around 7:30 a.m. EDT on Sunday, making it the best time to view.

5) As in any supermoon event, high tides are forecast because of the moon's proximity, but the effect is expected to be small.

6) Supermoons will get smaller in the future, since the moon is slowly propelling itself out of the Earth's orbit - it moves 3.8 centimeters farther from Earth each year

7) Forget about the myths that swirl every time a supermoon appears. There's no link to higher crime or bizarre behavior. Scientists say that's just lunacy.
