在荷兰天文学家克里斯蒂安·惠更斯发现土星环以及第一颗已知土星卫星——土卫六“泰坦”之后，这颗行星逐渐成为天文学家的关注焦点。
The planet was only just beginning to come into focus, in the metaphorical sense: The Dutch astronomer Christiaan Huygens had just recently revealed Saturn's rings and its first known moon, Titan.
这些环，有成千上万个，是由数十亿个冰和岩石的粒子所组成，这些粒子被认为是彗星、小行星和粉碎卫星的碎片。
The rings—there are thousands—are made up of billions of ice and rock particles, thought to be pieces of comets, asteroids, or shattered moons

科学家以此显示环绕恒星的目标，并显示此为通常与行星有关的巨大的红色尘环的一部分，这样，它少有可能为一颗矮星。
The scientists used that to show that the object orbited a star and was part of a massive red dust ring which is usually associated with planets - making it less likely to be a dwarf star.
