Saturday's full moon will be super-close to Earth, and will look even closer thanks to something called the "moon illusion." Because of the moon's elliptical orbit, every two decades or so it's a mere 211,600 miles from Earth. In these cases it is called a "perigree moon," and "for reasons not fully understood by astronomers or psychologists, low-hanging moons look unnaturally large when they beam through trees, buildings and other foreground objects," says NASA. (We have lots of those!) If you miss it, there's another one in 2029. [CNN]
