Supermoon set to shine Sunday

Supermoon Sunday is nearly here.

NASA says the moon will be closer to the Earth tomorrow than at any other time during the year - in fact, the upcoming Supermoon will be the closest encounter between the Earth and the moon until August 2014.

"The moon will reach its closest distance to the Earth at exactly 7:32 am (EDT), but because it will be peaking in the early morning hours, both 22 June and 23 June will put on similar shows," NASA says on its site. "So either day will be a good opportunity to see the larger-and-brighter-than-normal Supermoon."

The space agency says the Supermoon will be up to 14% larger and 30% brighter than a typical full moon.

"This is a result of the moon reaching its perigree - the closest that it gets to the Earth during the course of its orbit," the site says. "During perigree on 23 June the moon will be only about 360,000 km away, as compared to the 406,000 km away that it is at its furthest distance from the Earth."

NASA says there's no evidence that the Supermoon will drive folks batty.

"There should be nothing unusual except maybe for more people staring up at the moon, which should be a wonderful thing," NASA planetary geologist Noah Petro said.
