The only supermoon this year is coming up on Sunday


The supermoon - or perigee-syzygy - will be visible on Sunday as our moon passes by the Earth.

December's full moon will mark the beginning of a series SUPERLINE, two supertunia expected in January, which happens very rarely.

The cool thing about a supermoon coinciding with a full moon is that the Moon will appear brighter and bigger, hints the name supermoon. A "supermoon" occurs if the moon is at its closest approach to the Earth when it is full.

Skygazers are set to be treated to a "full cold supermoon" this weekend. This produces variations in the moons apparent size and brightness.

This will be the first time in 2017 when a supermoon lines up with a full moon.

That puts the moon almost 26,000 miles (41,842 kilometres) closer to Earth on Sunday than usual.

The moon will be visible from Earth with the naked eye, just as it always is.

You might remember that the moon reached its full moon apogee (farthest away) on June 9th this year.

With the moon being as close to Earth as it is, there is a significant impact on the tides.

The moon is slightly covered with clouds as it rises over the banking district in Frankfurt, Germany, Monday, Nov. 14, 2016.

According to NASA, "supermoon" is not an astronomical term, so there's no official definition or guideline for how close the full moon has to be near the perigee in order to be deemed a "supermoon". And it is most striking at moonrise and moonset when the moon is near the horizon.

Last year's supermoon saw the closest lunar approach in 69 years, but unfortunately the moon will not creep this close again until 2034.

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

"One reason why the horizon might appear more distant than the sky overhead is that our brains perceive the shape of "space" as a gently flattened dome rather than a perfectly round sphere", Drake wrote.

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. It won't be visible with the bright moon. "Still, it's a great excuse to just go out and look at the sky", says Nichols. "It's a fun way to get involved in science".
