The full moon in February is on the 19th and was known as the Snow Moon. The February full moon will be the closest full moon to Earth during 2019 at a distance 221,732 miles. This will make it the largest “Super Moon” of the year. The Full moon on September 14th is furthest away from Earth with a distance of 252,430 miles. The difference in size of the largest and smallest full moon is 253 arcminutes – about 13%. (There are 60 arcminutes in a degree and 360 degrees in a circle.) No matter how large the moon looks, with your arm outstretched, you can still cover it with the tip of your little finger.
