The story of the word

βολίς came from βάλλω, to throw, and named a javelin or a sounding lead dropped from a ship. French astronomers took it in the eighteenth century for fireballs, and English borrowed it from them. Geologists now use it in a looser way, for any large impactor whose composition is unknown, as in the bolide that ended the Cretaceous.
