The supermoon returns for a third time this summer on Sunday, marking the closest a full moon will get to Earth in 2014. The moon will be 221,796 miles from our planet at 1:46 p.m. ET on Sunday, just minutes before the official moment of the moon's full phase at 2:09 p.m. ET. It will be the largest moon since March 2011, according to Bob Berman of the Slooh virtual observatory. The Perseid meteor shower will hit its annual peak around Aug. 11 to 13. This isn't good news for those hoping to catch a glimpse of the meteors, as the just-past-full moon will overwhelm the shooting stars all night long.
