Supermoon 2017: How to see it in Chicago Sunday

The supermoon - or perigee-syzygy - will be visible on Sunday as our moon passes by the Earth. But what is a supermoon?

This Sunday the moon will be about 222,272 miles from the Earth. At that time, it will be a supermoon, the only one in 2017.

The moonrise will appear at similar times across the United Kingdom, with just a few minute differences from the north to the south. On average, the distance between the Earth and the Moon is usually 238,000 miles. Officially to obtain this title, the moon has to reach 90 percent of its closest approach, or Lunar Perigee. This distance varies from a low of 221,500 miles at perigee (moon closest to the Earth) to a high of 252,700 miles at apogee (Moon farthest from the Earth). It's called a supermoon and it only happens once this year.

National Geographic reported that the Dec. 3 supermoon will appear 7 percent larger and 16 percent brighter than a normal December full moon.

Despite what the popular term might suggest, the supermoon is in fact our regular moon, but much closer to Earth than usual. These differences are most noticeable when the moon is full. In 2016, the moon was the closest it had been to Earth since 1948.

While the moon is undoubtedly both bigger and brighter than usual, our eyes tend to trick us into seeing the moon as larger than it truly is.

Native Americans dubbed December's full moon the Full Cold Moon because it signals the beginning of winter when cold weather fastens its grip on much of the country until spring.

So, why is the moonrise the best time to view the supermoon?

While the supermoon can come out looking larger in photos (thanks to long lenses and editing) than it does when looking at it in person, Nichols says it is an incredible opportunity to get people interested in science and astronomy.

Just days after the end of hurricane season, now that we can look to the skies without trepidation, a bright treat will greet sky gazers Sunday night.

If you're dreading the beginning of Mercury Retrograde Dec. 3, you can counteract the smallest planet's bad mojo by setting your intentions under December's supermoon, which is happening the same day.
