Meteoriticists have long been puzzled by the fact that the most common meteorites, so-called ordinary chondrites, don't appear to have come from the most common asteroids, the S-types. Last week, however, a group of researchers attending the spring meeting of the American Geophysical Union here announced that the 31-kilometer-long S-type asteroid Eros now being orbited by the NEAR Shoemaker spacecraft is made of the same stuff as ordinary chondrites. That conclusion comes from NEAR Shoemaker's first-ever analysis of the elemental composition of an asteroid.
陨石学家长期以来一直对一个事实感到困惑，即最常见的陨石，所谓的普通球粒陨石，似乎并非来自最常见的小行星，即 S 型小行星。然而，上周，一群参加美国地球物理联合会春季会议的研究人员在这里宣布，目前正在由近地小行星会合探测器（NEAR Shoemaker）环绕飞行的 S 型小行星爱神星（Eros）的物质组成与普通球粒陨石相同。这一结论来自近地小行星会合探测器对小行星元素组成的首次分析。
