The moon will swing in 221,802 miles (356,955 kilometers) from our planet, and some believe that this phenomenon can rile tides, kick up extreme weather, spur natural disasters, and even affect the internal spirit of people and creatures. Some have even speculated that last year's supermoon, which occurred March 19, 2011 and was the closest since 1993, was the cause of the Tōhoku earthquake and tsunami in Japan.
Saturday's moon, which also falls on the 138th running of the Kentucky Derby and the 150th anniversary of Cinco de Mayo, is due to burn at least 16% brighter than normal. The best times to catch the supermoon are as it rises or sets. Check out the video below that NASA made to explain the supermoon of May 5th.
