今年最大的圆月Year's Biggest Full Moon Friday Night

The full moon last (Friday) night was the biggest one of the year as Earth's natural satellite reached its closest point to our planet.
Earth, the moon and the sun are all bound together by gravity, which keeps us going around the sun and keeps the moon going around us as it goes through phases. The moon makes a trip around Earth every 29.5 days. But the orbit is not a perfect circle.
The moon's average distance from us is about 238,855 miles (384,400 km). Friday night it was just 221,560 miles (356,567 km) away. It was 14 percent bigger in our sky and 30 percent brighter than some other full moons during the year, according to NASA.

Tides were higher Friday night, too. Earth's oceans are pulled by the gravity of the moon and the sun. So when the moon is closer, tides are pulled higher. Scientists call these perigean(近地点) tides, because the moon's closest point to Earth is called perigee. The farthest point on the lunar orbit is called apogee(远地点).
