Beschreibung
| Beschreibung | A simplified plot of the position of Venus with respect to the Earth (i.e. geocentric perspective). For this graphic, Venus and the Earth are assumed to be in coplanar concentric perfect circular orbits around the sun, and Venus' and Earth's orbital periods are assumed to be in an exact 8:13 ratio (so that the size of Venus' orbit with respect to the Earth's is set as the cube root of 8²/13² by Kepler's third law, or about 0.7234876 AU). The resulting 5-fold symmetric curve is sometimes called a "pentagram" (though it has little resemblance to a conventional 5-pointed star). The innermost loops near the center are where Apparent retrograde motion is observed. See Venus geocentric orbit curve simplified (pentagram).svg for this plotted as a series of points, instead of a continuous curve, and see Venus pentagram.png for an alternative more astronomically-correct (less simplified) plot. | ||
