“Super Moon” describes a new or full moon occurring at the same time the Moon comes within 90 percent of its closest approach to Earth in a given orbit.

It’s an event that happens four to six times a year, but Saturday night's full moon coincided  with the moon's arrival at its closest point in its orbit around the Earth, resulting in the biggest, visible full moon in North America in two decades.

"The last full Moon so big and close to Earth occurred in March of 1993," Geoff Chester of the U.S. Naval Observatory in Washington DC says in a recent NASA Science News story. "I'd say it's worth a look."

Officially, a “Super Moon” is called a  "Perigee Moon.”

"The full Moon of March 19th occurs less than one hour away from perigee – a near-perfect coincidence1 that happens only 18 years or so," added Chester.

Full moons vary in size because of the moon’s oval shape, according to the article. The moon is an ellipse with one side [perigee] about 50,000 km closer to Earth than the other [apogee]. Perigee moons are about 14 percent larger and 30 percent brighter than non-perigee moons – if the weather cooperates. Luckily, its was a clear night Saturday, which was perfect for moon watching.

Perigee moons are also known to cause higher tides, but nothing significant enough to worry about. And, despite Internet rumours, there is no risk of any natural disasters because of the moon, NASA said.

A super perigee Moon is still 356,577 km away, according to NASA.
