Skywatchers today will have a great opportunity to witness the ‘supermoon’, with the moon appearing brighter and larger than usual in the sky.

The planet will be about 7% larger and 15% brighter, with a slight difference noticed by human eyes.

“It’s hard for our eyes to distinguish these small changes in size when the Moon is high amidst the vastness of the night sky. But any time you catch a full Moon as it rises or sets,” NASA said.

This occurrence happens each year, when the moon sits opposite the sun in the sky, placing it 222,761 miles from Earth, closer than its average 238,900 miles.

NASA earlier said the earth will witness a ‘Supermoon Trilogy’ in December and January, in which the moon will be at or near its closest point in its orbit around Earth for three times.

The first occurrence will be on December 3rd, the second will be on January 1st, and the last one will take place January 31.

Since January 31 supermoon will be the second full moon of the month, referred to as a ‘Blue Moon’, a name some people give to the second full moon in a month.

The ‘Blue Moon’ happens every two and a half years, on average. With the total eclipse, it’ll be a royal spectacle indeed: a ‘super blue blood’ moon.
