Webb11 sep. 2008 · THE MOON'S ORBIT. Kepler's first law says that planets have elliptical orbits. As a result, the distance between a planet and the Sun changes rhythmically as the planet moves in its orbit. In many cases, this rhythmic change is rather subtle; for example, the Earth's distance from the Sun varies between 98.3% and 101.7% of its average value. Webb12 feb. 2024 · Planetary orbits are approximately elliptical. Explanation: In the 17th century Johannes Kepler showed that planetary orbits are ellipses. Newton's laws of motion confirmed this. Modelling planetary orbits as ellipses is quite accurate. In fact NASA publish the orbital parameters which define the ellipses for the orbits of the planets.

Webb18 nov. 2024 · The Earth's orbit is very nearly circular. The elliptical eccentricity is only 0.0167. In reality, the elliptical model is too idealistic. The Earth's orbit is constantly changing shape due to the gravitational effects of the other planets. One quite noticable effect is the time of perihelion.
