As a result of the optical illusion called the Moon Illusion, the full moon can look enormous when rising in the background of faraway objects on the horizon. The word "supermoon" was coined by Richard Nolle, an astrologer, in 1979.
A supermoon happens when the full moon occurs at approximately the same time in which the orbit of the moon makes it closest pass to earth.
When the full moon rises on Sunday night, December 3rd, it will be first and last supermoon of 2017. It has also been adopted by some with the term micro-moon or mini-moon when the full moon coincides with the apogee.
The December full moon, even when its not a supermoon, is known as the cold moon.
The moon's orbit around the Earth is not a flawless circle, meaning the distance between the two bodies grows and shrinks as the lunar planet plods eternal laps around us.
The moon will appear 7 percent larger and 16 percent brighter than usual.Читайте также: 'Lady Bird' sets record for highest approval rating on Rotten Tomatoes
The exact moment of the full moon is the morning of December 3 at 10:46 a.m. ET, (9:46 a.m. CT, 8:46 a.m. MT, and 6:46 a.m. PT), Space.com said.
The moon has to be no more than 363,711 km away from the Earth to be considered "super".
Full moons normally occur when the Earth is directly in line between the moon and the sun.
According to NASA, there will be supermoons in both January and February of 2018. The celestial event will be visible for anyone who is located somewhere without dense cloud cover, marking the final notable moon appearance of the year.
The supermoon will be visible in night skies around the planet, but the best time to see it will be just after sunset.При любом использовании материалов сайта и дочерних проектов, гиперссылка на обязательна.
