For those of you like me, who were uncertain as to what and why the recent ‘Supermoon’ occurred, I found this nice infographic from the Forbes website.
The moon’s orbit is an ellipse (an uneven circle), and as a result, the distance between the Moon and Earth varies throughout the month and the year. On average the distance is about 382,900 kilometers (238,000 miles). The point on the Moon’s orbit closest to Earth is called the perigee and the point farthest away is the apogee. The ellipse also varies slightly from year to year, with this years perigee moon being closest to the earth since 1948.
