In molecular orbital theory, we named orbits based on their symmetry.
在分子轨道理论中,我们基于轨道的对称性给它们命名。
Most known extrasolar planets reside in highly elongated, not circular, orbits.
大多数已知的太阳系外行星都居住在高度拉长而非圆形的轨道上。
They will likely then travel close enough to neighboring planets to disturb their orbits also.
然后,它们很可能会飞得离邻近的行星足够近,从而扰乱它们的轨道。
Let´s continue our discussion now by talking about orbits, especially those of the so-called periodic-orbit comets.
现在我们继续讨论,谈谈轨道,特别是那些所谓的周期轨道彗星。
