A super blue moon is a rare astronomical event that combines two phenomena: a supermoon and a blue moon.
A supermoon occurs when a full moon is at or near its closest point to Earth in its orbit, known as the perigee. This makes the moon appear larger and brighter than usual.
A blue moon traditionally refers to the second full moon in a calendar month that has two full moons. This happens because a full moon occurs approximately every 29.5 days, so occasionally, there are two full moons within a single month.
When these two events coincide, you get a “super blue moon.” Despite the name, the moon doesn’t actually appear blue; the term “blue moon” is just a quirk of the calendar.
Super blue moons like the one that occurred on Monday are quite rare, happening only once every few years.
