It is because the<br \/>\nplanet?Sun distance can be determined only through the Earth?Sun distance in the analysis. By<br \/>\napplying the law of equal areas for the Earth and the observed angular speeds of a planet over the<br \/>\nSun, the law of equal areas for planets can be re-constructed. Furthermore, for the periodicity of a<br \/>\nplanet to the Sun, the distance from each planet to the Sun may be expressed as an angular periodic<br \/>\nfunction. By coordinating with the observed data, this periodic distance function depicts an exact<br \/>\nelliptical path. Here, we apply relatively easy mathematical skills to illustrate the invariant<br \/>\nforms of planetary motions and indicate the key factors used to analyse the motions in complicated<br \/>\nplanetary systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this we design a simple and insightful way to achieve Kepler?s first two laws for planets.
