A supermoon is lighting up our skies, and this one shows up before sunset! 🌕 The next supermoon rises on December 4, as the Moon reaches perigee. That is its closest orbital point to Earth, where it can appear up to 14% larger and 30% brighter than a typical full moon. This dramatic effect is due to its elliptical orbit, and it's easiest to spot near the horizon, where our brains perceive it as even bigger. Look to the eastern sky before sunset on the 4th, or catch it again at moonset near sunr
