If WASP-18b somehow escapes imminent destruction by tidal forces, then astronomers will know that "our understanding of orbital dynamics, particularly tidal interactions, needs revision," says lead author Coel Hellier of Keele University in the United Kingdom.

如果 WASP-18b 以某种方式靠潮汐力逃脱了即将灭亡的命运，那么天文学家们将会认识到我们对轨道动力学的理解需要改变了，特别是对潮汐作用的理解更需要改变，该研究的首要发起人、英国基尔大学的科尔·赫利尔说。
