Abstract

Cometary particles returned by the Stardust Discovery Mission are primarily silicate materials of solar system origin. Some of the grains were formed at high temperatures close to the Sun, but then transported far out to the Kuiper belt region of the solar system before being incorporated in the comet.

摘要

星尘号探测任务带回的彗星颗粒主要是源自太阳系的硅酸盐物质。其中一些颗粒是在靠近太阳的高温环境下形成的，但随后被运送到太阳系遥远的柯伊伯带区域，之后才被纳入彗星之中。
