Answer:
Do superstition about comets and asteroids have scientific basis? No. By definition, a superstition is irrational and has no scientific basis. The actual threats posed by comets and meteors are much greater than the "portents" that are seen in Astrology. But no known civilization is known to have experienced them. Eclipses, moon phases, and the alignments of planets are other celestial phenomena that became associated with either fortunate or unfortunate occurrences. Superstitious beliefs draw connections between phenomena and objects that, based on scientific evidence, are unrelated. If a belief in such a connection has a scientific basis, then by definition the belief is not superstitious.
