We’re about to see a record-breaking supermoon - the biggest in nearly 70 years

Get ready folks, there is supermoon this November, and the Moon will be the closest to Earth and the last time it was close the year was 1948. On the eve of November 14, the Moon will appear nearly 30 percent brighter and up to 14 percent larger than an average full moon. So the next time the moon will come this close the year will be 2034, so, believe me, you really don’t want to miss this one.

The physics behind supermoon is a bit simple, since the Moon has an elliptical orbit, one side - called the perigee - is almost 48,280 km (30,000 miles) closer to Earth than the other side (called the apogee).

So when the Sun, the Moon, and Earth line up as the Moon circles Earth, that’s called syzygy (yep that’s right).

When this typical Earth-Moon-Sun system take place with the perigee side of the Moon towards us, and the Moon seems to be on the opposite side of Earth from the Sun, the result we get is called a c.

This perigee-syzygy causes the Moon to appear much bigger and brighter in our sky than normal, and it’s called as a supermoon - or a perigee moon.

Supermoons aren’t all that uncommon - we just had one on October 16, and after the November 14 super-supermoon, we’ll have another one on December 14.

This November the Moons is going to look the biggest it has in almost seven decades.

As the NASA explains:

"The full moon of November 14 is not only the closest full moon of 2016, but also the closest full moon to date in the 21st century. The full moon won’t come this close to Earth again until 25 November 2034."

"When the moon is near the horizon, it can look unnaturally large when viewed through trees, buildings, or other foreground objects. The effect is an optical illusion, but that fact doesn’t take away from the experience."

Here are a couple of examples from the supermoon occurred in 2014:
