1 前言可以认为太阳系上所存在的小型物体(小行星和彗星)保留着太阳系当初诞生时的物证,对探索太阳系的起源非常重要。在1986年哈雷彗星接近太阳时,世界上许多国家和空间组织合作共发射了6颗探测器,绕哈雷彗星飞行观测哈雷彗星,此后还发射了木星探测器,在飞往木星的过程中绕多颗小行星飞行,对这些小行星进行观测,20世纪90年代后半期,发射了多颗小天体探测器。2000年NEAR探测器进入绕
1 Preface It is believed that the small objects (asteroids and comets) that exist in the solar system retain the physical evidence of the birth of the solar system and are of great importance in exploring the origin of the solar system. When Halley’s comet approached the sun in 1986, a total of six probes were launched in cooperation with space agencies in the world and Halley’s comet was observed flying around Halley’s comet. Later, a Jupiter probe was launched and the Jupiter probe was fired around in the process of flying to Jupiter Asteroid flying, observing these asteroids, the second half of the 1990s, launched a number of small celestial detectors. 2000 NEAR detector into the winding
