It was there at perigee on Sunday night.

周日晚上的近地点会出现超级月亮。

Each month, the Moon passes through perigee (the point closest to Earth) and apogee (the point farthest from Earth).

每个月，月球都会经过近地点（离地球最近的点）和远地点（离地球最远的点）。

The reason is because it was at Perigee at the closest point of its elliptical orbit around the earth.

原因是因为它位于近地点，是其绕地球椭圆轨道的最近点。

And at the perigee of the orbit, or the lowest point, it dips into the earth atmosphere and basically burns back up.

在轨道的近地点，或最低点，它浸入地球大气层，基本上燃烧起来。

When there is a full moon on the perigee side of its orbit, it's bigger and brighter than usual, and can look especially large close to the horizon due to an optical illusion.

当满月位于其轨道的近地点一侧时，它看起来会比平时更大、更亮，而且由于光学错觉，在接近地平线时看起来会特别大。

Li explained that after separating from the rocket, the cargo craft moves from the perigee orbit to that of the space station by means of long-range autonomous guidance and near-range autonomous control to achieve fast-docking.

李解释说，货船与火箭分离后，通过远程自主制导和近距离自主控制，从近地点轨道移动到空间站轨道，实现快速交会对接。
