Although micrometeorites of cometary origin are thought to be the dominant component of interplanetary dust, it has never been possible to positively identify such micrometer-sized particles. Two such particles have been identified as definitely micrometeorites since their abundances of volatile and nonvolatile trace elements closely match those of primitive solar system material.
虽然彗星来源的微陨石被认为是星际尘埃的主要成分，但一直无法对这些微米级大小的颗粒进行明确的鉴定。由于这两个颗粒的挥发性和非挥发性微量元素丰度与原始太阳系物质非常匹配，因此被确定为微陨石。
