from the greek word comet, meaning "to comet"
Depends. Halley didn't discover the comet, mearly recognised it as a periodic comet from data recorded by Petrus Apianus in 1531 (German) and Johannes Kepler in 1607 (also German). Halley (English) predicted when the comet would return but did not live long enough to see it.

The name comet came from the Greek word komē meaning "hair of the head". Aristotle used this word to mean a luminous tail of a comet. Aristotle also used the derivation komētēs meaning "wearing long hair" to use as a noun meaning comet and to describe comets as "stars with hair". This Greek word was adopted as the Latin word comētēs and later comēta. Comēta is the earliest English forebear of the now "comet".
