A supermoon happens when a full moon coincides with the moon’s closest point to Earth. Supermoons typically occur three to four times a year, and when they do, they will appear consecutively. On Nov 5, we’ll see the closest supermoon of 2025. Supermoons aren’t just beautiful to look at; they also have effects here on Earth. As "spooky season" begins and with the full moon being in the first week of October, don’t be surprised if it looks a little brighter than usual.
