Special guest appearance next to 'Blue Moon' on August 30

According to the National Aeronautics and Space Administration (NASA), a supermoon occurs when the moon is full and closest to the Earth in its orbit - about 357,344 km away. This phenomenon usually occurs once every 3-4 years. However, if it occurs twice in a month, the second supermoon will be called a "super blue moon".

This supermoon will be accompanied by the presence of Saturn. Saturn will appear as a bright point of light just 5 degrees above and to the right of the moon. However, actually seeing the planet may be difficult due to the bright light from the moon.

Not only is it brighter, the supermoon is also 14% larger than a regular moon.

This week's super blue moon will be an extremely rare sight. According to Italian astronomer Gianluca Masi, founder of the Virtual Telescope Project, the phenomenon won't occur again until 2037.

According to the Encyclopaedia Britannica, the term “blue moon” originates from a 16th-century idiom that refers to something that never or rarely happens.
