13 full moons, including two supermoons and a blue moon, will be shining in 2020

Astronomy experts say two supermoons will shine in the sky this year and in October there will be two full moons, including a 'blue moon' that on Halloween.

Although blue moons occur once every two or three years, they are even more rare on Halloween, according to AccuWeather meteorologist Brian Lada.

He told Syracuse.com: “After the blue moon on Oct. 31, 2020, trick-or-treaters will need to wait until 2039 to see the next blue moon on Halloween."

WHAT IS A SUPERMOON?

Supermoons are moons that become full when their orbits are closer than average to the Earth — making them appear to be slightly bigger and as much as 30% brighter than ordinary full moons.

Although the precise definition varies in the astronomy world — and some experts say the average star gazer won’t notice the size and brightness difference — most say a supermoon is a moon that tracks less than 223,000 miles from the Earth during its full phase. (Some say any full moon that is 226,000 miles or closer to the Earth can be classified as a supermoon, and others set the cutoff at the precise distance of 223,694 miles.)

Regardless of the exact definition, astronomy websites seem to agree that 2020 will feature at least two supermoons — one on March 9 and another on April 7. Worth marking down on your calendar: Space.comsays the April full moon will be the biggest of the year, because it will be the closest one to our planet.
