Whether it is was the prospect of standing outside in the cold weather, cloud cover, or your bad memory that meant you missed last night's supermoon then fear not. Supermoons appear about 14 per cent bigger and about 30 per cent brighter than a normal full moon as seen from the Earth.
Nasa described the event as the first in a "supermoon trilogy", with two more to come on January 1 and January 31.
The supermoon tends to be brighter and appear to be larger than its usual size.
The moon is not actually that much closer to the earth, it is just our brain that interpret it as a lot closer.
A supermoon rises in front of a replica of the Statue of Liberty sitting atop the Liberty Building in downtown Buffalo, N.Y. on December 3, 2017. The supermoon is a full moon that occurs when the moon is closest to the earth. That's because it's the last full moon of the year.
The full moon that occurs at this time in the year is nicknamed the Frost Moon due to Native American traditions or the Moon Before Yule as it is the last full moon of the season.
The moon also needs to be full which happens once every 29.5 days, when the sun fully illuminates the moon.
