A supermoon happens when the Earth is between the sun and the closer-than-usual moon.

当地球太阳与行经近地点的球中间时，就会出现超级亮的景观。

It was there at perigee on Sunday night.

周日晚上的近地点会出现超级亮。

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.

当满其轨道的近地点一侧时，它看来会比平时更大、更亮，而且由错觉，在接近地平线时看来会特别大。

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。

The moon is about 48,000 kilometers closer to Earth on one side of its orbit than the other.

球行经近地点时，球距地球的距离与另一端相差约48000公里。

We call this the perigee, the day after the full moon.

我们称之为近地点，即满后的第二天。

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，基本上燃烧来。

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

每个，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）。

These two cute red hats are called perigee and are to symbolise ideas, freedom and the French spirit.

这两个可爱的红色小帽子名为“近地点”， 象征着思想、自由和法国精神。
