BreakingNews·191010 - 土星现在是拥有卫星最多的行星

Astronomers have promoted Saturn as the planet with the most moons. Saturn has overtaken the solar system's largest planet Jupiter as the "king of the moons". The astronomers recently discovered 20 new moons orbiting Saturn, which brings the planet's total number to 82. This edges out Jupiter, with 79 celestial bodies, into second place. Each of the newly-discovered moons is at least 5km in diameter. Seventeen of them orbit Saturn backwards and take more than three years to complete one orbit of Saturn. The astronomers found the moons using the powerful Subaru telescope, located on Hawaii. The research team will now look for moons that are around a kilometer in diameter.

天文学家认为土星是拥有卫星最多的行星。土星已经取代太阳系最大的行星木星，成为“卫星之王”。天文学家最近发现了20颗围绕土星运行的新卫星，使土星的卫星总数达到82颗。这将拥有79个天体的木星挤到了第二位。每个新发现的卫星直径至少有5公里。其中有17颗卫星是反向绕土星运行的，而完成一颗土星的轨道需要3年多的时间。天文学家使用位于夏威夷的强大的斯巴鲁望远镜发现了这些卫星。研究小组现在将寻找直径约一公里的卫星。

Lead astronomer Dr Scott Sheppard commented on the perceived origins of the new moons. He said: "We don't think they formed with the planet. We think they were captured by the planet in the past." He posited that Saturn sucked in a swirling mixture of gas and dust to form the moons. Dr Shepperd added: "We think these moons interacted with that gas and dust. These were comets or asteroids that happened to be passing by....They were captured into orbits around the planet rather than falling into the planet. We think these are the last remnants of what formed Saturn." The moons will be named in a competition after giants from Gallic, Inuit and Norse mythology.

首席天文学家斯科特·谢泼德博士对新月的起源进行了评论。他说:“我们认为它们不是由行星形成的。我们认为它们在过去曾被地球捕获。”他假设土星吸入了一种旋转的气体和尘埃混合物，形成了卫星。Shepperd博士补充道:“我们认为这些卫星与气体和尘埃相互作用。这些是碰巧经过的彗星或小行星。它们被捕获进入围绕行星的轨道，而不是落入行星。我们认为这些是土星形成的最后残余。”这些卫星将在一次竞赛中以来自高卢、因纽特和挪威神话的巨人来命名。
