Opsomming
| Beskrywing | 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 (with Venus' orbit having a radius of 0.724 AU), and Venus' and Earth's orbital periods are assumed to be in an exact 8:13 ratio. The position of Venus with respect to the Earth is plotted approximately every 13 and a half hours over the 8 year period (a total of 5,200 points). 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 Line (pentagram).svg for this plotted as a smooth continuous curve instead of a series of points, and see Venus pentagram.png for an alternative more astronomically-correct (less simplified) plot. | ||
