On August 30, we will witness a rare celestial event- Super Blue Moon, which occurs when a full moon happens during the period when the moon is closer to the Earth. This phenomenon happens because the moon's orbit around Earth is elliptical and not circular. This means there are times when the moon is farther away — at apogee — and times when it is closer — at perigee. The distance between Earth and the moon during perigee and apogee ranges from around 220,000 miles (350,000 kilometers) to 253,000 miles (408,000 km), a difference of around 14%.
Contrary to the name, the moon does not appear blue in color. It is just a term for two full moons in a month.
