开普勒第三定律，也即调和定律，清楚地表明了行星公转周期与其离日距离之间的关系。

The third one, the law of periods, allows us to establish a clear relationship between a planet's orbital period and its distance from the sun.

低廉的花费，相对快速的几个月的公转周期使得微微卫星在教育方面上的价值无法估量。

The low cost and relatively quick turnaround time of a few months makes nanosatellites invaluable from an education perspective.
