It was there at perigee on Sunday night.

周日晚上近地会出现超级月亮。

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（离地球最近）和远地（离地球最远）。

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

在轨道近地，或最低，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.

当满月位于其轨道近地一侧时，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，从近地轨道移动到空间站轨道，实现快速交会对接。
