  通过长期的天象观测,人类至今已发现1600多颗彗星绕太阳运行。纷繁有趣的彗星世界,使人们遐想万千。彗星究竟诞生何处,一直是天文学家们探索的课题。近年,美国“哈勃”天文望远镜发现太阳系边缘有一个庞大的彗星“摇篮”。“摇篮”呈环状,内环位于天王星轨道之外,外环则超出了冥王星轨道。这个“摇篮”中约有2亿个彗星 “婴儿”,它们主要由直径10~500千米的冰块和石块组成。由于太阳系中各大星球错综复杂的引力作用,“婴儿”一旦被什么外来碎块撞击,便偏离自己原来的轨道而成为“游子”。“游子”因太阳强大的引力,朝着太阳方向飞去。途中,冰块等物质受太阳光热而蒸发,并在太阳风的作用下飘成扫帚状,成为它美丽的大尾巴。
