When this happened a year ago, the moon appeared up to 14 percent larger and 30 percent brighter than normal.
This weekend, sky-watchers can look forward to a phenomenon that hasn't yet graced the skies this year: a supermoon.
As it reaches fullness, the moon will also be making its closest approach to Earth around the same time, designating it a "supermoon".
The moon will be visible to see on Sunday after 5 p.m. when it begins to rise, however, it won't officially be a Supermoon until it is at its closest point to Earth, which will be at approximately 4 a.m. on Monday.
It'll be almost full Saturday night with clear skies for viewing.
The finest time span to observe the supermoon is right after the moonrise and just before the sunrise, but the moon will stun throughout its voyage across the sky. This is because it's a Supermoon, which is a full moon that's closer to the Earth than normal.
First (and last) supermoon of 2017 is coming
When's the best time to view the supermoon?
The supermoon which was last seen on November 14, 2016 is set to re-appear tomorrow evening on December 3.
"The supermoons are a great opportunity for people to start looking at the Moon, not just that once but every chance they have!" says Noah Petro, a research scientist from NASA's Goddard Space Flight Center. You can also watch a livestream from the Virtual Telescope Project. NASA calls it the supermoon trilogy, with the next two occurring on January 1 and January 31.
If you miss the first viewing, another good time to sneak a peek is when the supermoon reaches its peak at 4 a.m. on December 4.
By some measures, Sunday night's full moon is the only supermoon of 2017.More news: MacOS High Sierra bug allows access to Mac without a password
