距星 的英文怎麼說

This greatly simplifies the various analyses, for example, their relative apparent magnitudes are equal to their relative absolute magnitudes

當然，成員星和地球的距離亦會差不多，因此大大簡化了對成員星的分析。

Two stars have the same absolute magnitude. one is thousand times farther away than the other. what is the difference in apparent magnitudes ? which magnitude larger

兩顆星具有相同的絕對星等，其中的一顆比另一顆距離遠1000倍，它們的目視星等有何不同？哪一個的星等數值大？

The longer the period, the brighter the star is. thus, by measuring the period of a cepheid variable, we know its absolute magnitude, hence, we can tell how far it is away by comparing with its apparent magnitude

所以，只要知道某一造父變星的周期，我們便可得知它的絕對星等，只要和它的視星等作比較，便可以求得它和我們的距離。
