If it did, planetary orbits would be disrupted, causing the Earth to drop into the sun or be tossed out into deep space.

如果它做到了，就会破坏行星轨道，导致地球落进太阳或被甩进外太空。

These gravitational effects have a subtle, but apparently significant influence on the evolution of planetary orbits in the solar system.

这些引力作用对太阳系行星轨道的演变具有微妙而又明显重要的影响。

Very accurate predictions of planetary orbits require corrections to the central-field approximation.

想要非常准确地预言行星的轨道，就需要对中心场近似进行修正。

"The eccentric planetary orbits seen in these systems are essentially scars from past disruptions caused by the companion star, " co-author Sean Raymond, of the University of Bordeaux and the National Center for Scientific Research in France, said in a statement.
