Summer of Super Moons
Most of us were introduced to the concept of a "Super Moon" by the news media in June of 2013. It was called a "Super Moon" because the moon was at its perigee, or closest point to Earth in its oval-shaped orbit, making the moon appear much larger and brighter than usual. This summer, we will experience three consecutive Super Moons, the first of which just occurred in July, continuing on into August and September.
This video from Science @ NASA explains the concept of the "Super Moon" in more detail, and lets you know what to expect if you plan on having a Super Moon viewing party of your own.
