How to watch the only visible "supermoon" of 2017 this weekend

During moonrise, "you will experience the optical illusion which makes the moon appear larger when viewed against the horizon", Faherty said.

The previous supermoon was the closest to Earth since 1948, and we won't see another like that until 2034.

"The supermoon gets headlines because the moon's a little bigger and a little brighter, but people get frustrated that they can't always tell the difference".

December's full moon - which is traditionally known as the Cold Moon - will appear in the sky 14 percent bigger and 30 percent brighter than usual on Sunday (3).

A supermoon, of course, is no bigger than the moon at any given time, but the term refers to when a new or full moon coincides with the lunar orbit coming in close proximity to Earth, according to National Geographic. That's because the Earth is closer to the sun, and the sun's gravity tugs the moon closer to the Earth.

So when will you be able to see the supermoon?

The Cold Moon won't actually reach the closest point to the Earth's surface until Monday morning, but Sunday night is when it will be at its most striking.

Plan discussed to replace Rex Tillerson as Secretary of State
Tillerson was reported in October to have privately called Trump a " moron ", something the secretary of state sought to dismiss. Trump has given final approval to the plan", but that Chief of Staff John Kelly has drawn it up and widely circulated it.

That's because the timing has to be just right. In fact, the change in the moon's apparent size throughout its orbit is imperceptible to the unaided eye. The moon will still be super-sized when it becomes visible that evening and will officially reach its perigee at 3:45 a.m. ET on December 4.

Guess what: It's supermoon time!

What's the best way to photograph the supermoon?

Bill Ingalls, a NASA photographer, says that those capturing the event through their smartphones have to focus on the correct light balance.

For everyone waiting to catch a glimpse of the last supermoon of 2017, taking pictures to preserve the moment can be easy.

"Tap the screen and hold your finger on the object (in this case, the moon) to lock the focus".
