OK, it's a bad gag, I know. But the movie Man of Steel isn't the only thing that's "super" about June this year. The closest full Moon of 2013 occurs on June 23, when it will be 356,991 kilometres from Earth, within 600 kilometres of its closest possible approach. When the Moon is closest to Earth in its orbit, it also appears just a bit larger in the sky. But that's if you're really paying attention, however!
