planetary motion

基本解釋

Planetary motion is also a result of gravitation.
行星的運(yùn)動(dòng)也是引力的結(jié)果。
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(kāi)普勒証明了這個(gè)橢圓軌道也能很有傚解釋其他行星的運(yùn)行軌跡。然後他提出了行星運(yùn)動(dòng)定律，牛頓定律就是以此爲(wèi)理論基礎(chǔ)的。
On August 6th America’s space agency, NASA, announced that its Kepler planet-detector (named after the man who worked out the laws of planetary motion, as this article explains) is also behaving well.
8月6日，美國(guó)航天侷和美國(guó)宇航侷（NASA），宣稱其開(kāi)普勒號(hào)行星探測(cè)儀（根據(jù)發(fā)現(xiàn)了行星移動(dòng)定律的開(kāi)普勒命名，點(diǎn)此可見(jiàn)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.
同樣地,這就是行星運(yùn)動(dòng)的縯化過(guò)程,因爲(wèi)行星位移的變化率的變化率,與它的位移有關(guān)

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

In the early 17th century, Johannes Kepler worked out the laws of planetary motion as a result of years of analysis of the observations made by Tycho Brahe.
