作为例子,我们计算了目视双星ADS 9446的双曲线轨道。
The hyperbolic orbit of and its mass the visual binary star ADS9446 is determined as an example.
现在,牛顿理论认为,有一些彗星沿双曲线或抛物线运行,永远不再返回;另外一些彗星沿普通的椭圆轨道运行。
Now according to Newtonian theory, some of them moved in hyperbolas or parabolas never to return; others moved in ordinary ellipses.
