摘要
用简化模型 (行星在同一平面内绕太阳作匀速圆周运动 )分析了行星相对于地球的运动 (视运动 )。给出了视运动的运动方程 ,证明了行星视运动的轨迹为圆外旋轮线。讨论了行星的顺向运动与逆向运动。给出了关于水星、金星、火星、土星。
Using a simplified model(revolution of planets round the sun are uniform circular motions in a plane), the apparent motion of planets relative to the earth is analyzed. Equation of the relative motion is derived. It is proved that the apparent trajectories are exterior trochoids. Counterclockwise and clockwise motion (retrograde) are discussed. Numerical results are given for Mercury, Venus, Mars, Saturn and Jupiter.
