The dazzling full moon sets behind the Very Large Telescope in Chile's Atacama Desert in this photo released June 7, 2010 by the European Southern Observatory. The moon appears larger than normal due to an optical illusion of perspective.

*If you haven’t heard, today, this (Saturday) afternoon, the moon will be the closest it’s been to Earth in more than 18 years.

The “supermoon,” as observers have dubbed it, will appear at 3 p.m. ET at a distance of 221,565 miles away. It will appear 14 percent larger and 30 percent brighter than your average full moon, weather permitting.

The reason why the moon will be so much closer is due to a fluke of orbital mechanics.

But don’t be alarmed: Although the supermoon will result in a dramatically large range of high and low ocean tides-which could result in flooding problems if combined with a coastal storm at the same time-it won’t cause a natural disaster.
