单词 | antitail |
释义 | antitailantitailA small spiky taillike structure on a comet that, unlike most comet tails, seems to point toward the Sun. It is usually only seen when the observer is in the plane of the cometary orbit. The particles responsible for scattering the sunlight are much larger than those that produce the normal dust tail.antitail[¦an·tē¦tāl] |
