Poseidon Supermoon

By: Anthony Ayiomamitis


Region: Europe

Site: Cape Sounion - Greece

Date: 2012 May 5

As seen on the Astronomy Picture of the Day and the National Geographic News the Full Moon hangs heavy over the Temple of Poseidon on Cape Sounion, south of Athens, in the early evening twilight. Due to the moon's egg-shaped orbit, our natural satellite is at perigee—its closest approach to Earth—about once a month. The term "supermoon" was coined in 1979 to describe a full moon that coincides with perigee. The full moon of 2012 May 5 was the largest of the year. However as the word supermoon might resemble, the angular size of the moon does not change that much, not notable to inexperienced eyes. Supermoons are just slightly larger in apparent size.
