    — And They made by the lifting of Their hands, each god according to his sign, the Bright One with the flaring tail to seek from the end of the Worlds to the end of them again, to return again after a hundred years. Man, when thou seest the comet, know that another seeketh besides thee nor ever findeth out.
  2. A celestial phenomenon with the appearance of such a body.

词源

From Middle English comete, partly from Old English comēta and partly from Old French comete, both from Latin comētēs, from Ancient Greek κομήτης (komḗtēs, “longhaired”), short for ἀστὴρ κομήτης ([astēr] komētēs, "longhaired [star])" and referring to the tail of a comet, from κόμη (kómē, “hair”). Compare English faxed star and Latin crīnīta stēlla (“comet”, literally “(long) haired star”).
