The super moon is actually the result of two phenomena occurring at the same time. The moon’s orbit around the earth is not perfectly circular . It has a somewhat oval shape . So it has closer points and farther points. The closest point is called the perigee and the farthest, the apogee. If a full moon occurs during the perigee , we have a super moon. The result is a moon that appears 14 percent bigger and 30 percent brighter than a full moon at apogee. .

The best time to see this super moon in Japan will be around 8:30 p.m. That is when the moon will come within 360,000 km of Earth .
