土星环、希伯利翁(Hyperion)和可能还有泰坦(Titan)在1亿年前的月球碰撞中形成,重塑了这个系统。 Saturn’s rings, Hyperion, and possibly Titan formed 100 million years ago from a moon collision, reshaping the system.

一项新研究表明，土星环、卫星海伯利昂，以及可能的土卫六，都是大约一亿年前由两颗古老卫星碰撞形成的，这对早期的理论提出了挑战。 A new study suggests Saturn’s rings, moon Hyperion, and possibly Titan formed about 100 million years ago from a collision between two ancient moons, challenging earlier theories. SETI研究所(SETI Institute)的研究人员和其他人的模拟显示,一个大型原月与一个较小的原月相撞,引发了一系列重塑土星系统的事件。 Simulations by researchers from the SETI Institute and others indicate a large proto-moon collided with a smaller one, triggering a chain of events that reshaped Saturn’s system. 这种撞击可能解释了泰坦星目前的轨道、环的青春、希伯利翁的奇形异状以及远方月球的倾斜轨道。 This impact may explain Titan’s current orbit, the youth of the rings, Hyperion’s odd shape, and the tilted orbits of distant moons. 这些结论与卡西尼飞行任务数据一致, 并表明土星的月亮仅仅在4亿到5亿年前就经历了重大重组。 The findings align with Cassini mission data and suggest Saturn’s moons underwent major reorganization just 400 to 500 million years ago.
