History for comet
The tail of a comet looks rather like long hair streaming behind the head. The ancient Greeks named comets with the word komētēs, which means literally “long-haired.” This word comes from the noun komē, “hair on one's head” or “shock of hair.” The English word comet came from the Greek name for comets.
