On July 13, the night sky was dominated by the largest and brightest moon, called a “Supermoon”.
It began at 12.08 AM IST and the Moon appeared as much as 14 per cent brighter and 30 per cent brighter, according to Space.com. But what does that mean and how does it happen?

On this date, the full supermoon lie 222,089 miles (357,418 km) from Earth. That’s in contrast to its average distance of about 240,000 miles (385,000 km).

Full moon and lunar perigee (when the moon is closest to Earth in its monthly orbit around our planet) fall on the same day in July. The moon’s orbit around Earth is not circular, it’s ellipticalSo the moon is sometimes closer to Earth, and sometimes farther away. Astronomers have long called the moon closest to Earth a perigee or perigean moon. But the idea of a full moon that’s closer to Earth than average didn’t catch on until the term supermoon was coined.
