On Sunday night, December 3rd, 2017, the moon will be at it's closest to the earth in it's orbit around us, so it will appear larger than normal resulting in what they call a Super Moon. It will be the one and only super moon this year, and at 4:00am ET, the moon will be a mere 222,443 miles from the Earth's surface. At that time it will appear 7% larger than normal, and be a bit brighter than normal. Although it won't be as bright as last years super moon which was the closest it's been to Earth in 68 years and is the closest it will be until 2039. As the moon nears the horizon, the light from it must pass through a greater distance of the Earth's atmosphere causing the moon to appear larger.
January 2018 also brings 2 more super moons. The first full moon of the year will be a super moon called the Wolf Moon, and will occur on January 2nd. The second full moon is not only a super moon, but is also considered a "blue" moon since it's the second of the month. This also happens to be a full lunar eclipse, and will be visible in the western part of North America, the Pacific, and eastern Asia. The rare event will occur on January 31st.
