When is the next supermoon?
The next supermoon will be on Thursday, Dec. 4, 2025. It will officially reach its full moon phase at 6:14 p.m. EST (2314 GMT), local moonrise times are dependent on location. This will be the third and final supermoon of 2025.
A supermoon occurs when the full moon coincides with the moon being at the point in its orbit within 90% of its closest approach to Earth, called perigee. This makes the moon appear slightly brighter and closer than usual, though the difference is difficult to notice with the naked eye.
