A blue moon is the second full moon in a month.
Because the new moon to new moon cycle lasts 29.5 days, a time comes when the full moon occurs at the beginning of a month, and there are days left still for another full cycle to be completed.
Such a month, in which the full moon is seen on the 1st or 2nd, will have a second full moon on the 30th or 31st.
According to NASA, this happens every two or three years.
Despite its name, a blue moon isn't blue
A super blue moon combines a supermoon and a blue moon.
A supermoon occurs when the moon aligns closely with Earth during its orbit, making it appear larger and brighter.
