Supermoon this Saturday will be Brighter and Bigger

Full Moon - BSN

(Best Syndication News) - A supermoon is going to appear this Saturday, May 5, 2012. The nickname “supermoon” comes from the idea that the moon appears larger and brighter than it typically would because its elliptical orbit causes a closer path. The astronomical name is full moon at perigee.

Nasa estimates the moon to appear 14 percent larger and around 30 percent brighter than usual. Dr. James Garvin, chief scientist at NASA's Goddard Space Flight Center said that their Lunar Reconnaissance Orbiter LRO mission is able to track the distance differences from the Earth and the Moon, and there really is not much difference.

McMaster astronomer Robert Cockcroft, manager of the university’s McCallion Planetarium explained that most people really would not notice the difference that much. Additionally the tide increase from the gravitational pull is only an increase of two to three centimeters from the supermoon event.

In 2011, a supermoon appeared in March, which also piqued the interest of many. Even despite the hype, astronomers can get a better view of the moon tonight. Casual observers may also enjoy the full moon and enjoy the view. The best time to appreciate the size of the moon is when it first appears on the horizon. The supermoon effect will look the most dramatic at this time.
