From NASA: Supermoons are full moons that appear bigger in the sky than usual, though the difference may not be noticeable to the casual observer. During a supermoon, the full moon can appear up to 14% larger and 30% brighter than when it is at its farthest from Earth. That’s because it coincides with the moon's arrival at perigee, the closest point to Earth in its orbit.
And the Pink Moon doesn't appear pink. It was named for phlox, an early-blooming spring flower.
