Kepler went on to show that an elliptical orbit is sufficient to explain the movement of the other planets and to devise the laws of planetary motion that Newton built on.
接著開普勒證明了這個(gè)橢圓軌道也能很有效解釋其他行星的運(yùn)行軌跡。然后他提出了行星運(yùn)動(dòng)定律，牛頓定律就是以此為理論基礎(chǔ)的。

8月6日，美國航天局和美國宇航局（NASA），宣稱其開普勒號行星探測儀（根據(jù)發(fā)現(xiàn)了行星移動(dòng)定律的開普勒命名，點(diǎn)此可見詳細(xì)介紹）現(xiàn)在運(yùn)行得十分良好。

Then again, you will find the evolution of the planetary motion, because the rate of change of the rate of the change of the position is connected to the position.

Kepler is famous for discovering the three laws of planetary motion, laws which Isaac Newton later re-derived with his universal theory of gravitation.
