Supermoons happen when the Moon is at or close to perigee, the closest point in its orbit around Earth. 4 consecutive supermoons (5/6/2020) (WSLS)We’ll have four supermoons in a row again next year, 2022, 2023 and 2024. You may be wondering if these strings of consecutive supermoons are rare. There are sliding windows of time where supermoons happen three, four or five times in a row each year. If you miss Thursday’s supermoon, you won’t have another chance to see one until March of next year.
