The Third Law of Kepler gives the relation between the periodic time of a planet, and its distance from the sun.
Of course, we now know not only what the connection between the planet's distance and the planet's periodic time actually is, but we also know that it is a necessary consequence of the law of universal gravitation.
It is possible, from the shape of its orbit, that it has a periodic time of nine thousand years, or that it may have a parabolic orbit, and never return.
There are certain things that are easy to determine, such as size, density, periodic time, velocity, etc.
Thus the earth's periodic time is one year, and that of the planet Jupiter about twelve years.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "periodic time" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
