PAA ( Piecewise Aggregate Approximation) is a method for representing time series by sliding an equal-width window on the data and dividing the data into segments.

滑动聚集平均近似PAA（Piecewise Aggregate Approximation）是一种表示时间序列的方法，它通过时间序列上滑动一个等宽的滑动窗口将时间序列分成小的区段。

But it's in the habitable zone because Proxima Centauri is a red dwarf star about 100 times fainter than the sun.

但因为比邻星是一颗红矮星，它比太阳暗100倍左右，因此行星位于宜居区。

moreover, given ingenious mission design, it might be possible to visit the nearby red dwarf star proxima centauri as well.

不仅如此，若项目设计精妙，它可能也能访问附近的红矮星比邻星。

The nearest star, Proxima Centauri, has a planet orbiting it not much bigger than Earth.

有一颗大小与地球相近的行星围绕着距离太阳最近的恒星——半人马座比邻星运转。
