Comets: structure, orbits, and effects

Etymology and naming origins

The name “comet” comes from Old English “cometa,” which was borrowed from Latin “comēta” or “comētēs.” Latin itself traces back to Greek “komētēs” (κομήτης), meaning “wearing long hair,” reflecting an older association of comets with long, hairlike tails. Etymologically, “komētēs” is derived from “koman” (κομᾶν), “to wear the hair long,” which comes from “komē” (κόμη), “the hair of the head.” In Greek usage, “komē” could also mean “the tail of a comet,” linking the word’s origin directly to the visual appearance of comets’ tails. The article also notes a dedicated astronomical symbol for comets (Unicode U+2604 ☄ COMET), depicted as a small disc with three hairlike extensions.
