Astronomers call it "perigee", and when the Moon reaches its closest distance on February 19, it would seem to be much bigger and brighter than an ordinary full moon.
On that special Tuesday, starting at roughly 10:53 a.m. EST, the moon will be at its fullest while at a distance of about 221,000 miles from Earth, which is 17,000 miles closer than the average distance, according to USA Today.
It is called the snow moon because it occurs during the coldest time of the year.
The final supermoon, known as the "Full Worm Moon" will take place on March 21.
NASA reports that the moon will appear up to 14 percent bigger and 30 percent brighter than a full moon at its farthest point from Earth.
Although closer to the Earth, this week's supermoon will not be as colourful as last month's super blood moon eclipse that turned the moon a stunning shade of orange.
A full moon occurs every month when we can see the moon in its entirety.

The moon will technically reach peak fullness next Tuesday morning, February 19, 2019, at 10:54 a.m. EST, but won't be visible to most in the U.S.at that time.
February's moon has also been called the bone or hunger moon due to the lack of food available in the winter. If you are hoping to capture a good "supermoon" photo, catching the moonrise is your best bet.
When is the next full moon?
The first supermoon was the "Blood Wolf Super Moon" on January 21 and the third will take place on March 21. And while you will have to settle for normal-sized full moons for the rest of the year, there are still a few more moon-related astronomical events to look out for this year. When this happens, light from the Sun refracts around Earth, making the moon appear red.
