Two of these relatively close by were reported by Kazimierz Kordylewski as harboring faint nebulosities, perhaps due to clouds of dust.  The impact hypothesis of the formation of the moon posits that a Mars-sized body formed at one of these points and then collided with the Earth, creating our moon.  They were predicted in 1772 by their namesake, and in 1906 Max Wolf discovered the first object occupying one of these locations with his observation of a Trojan asteroid.  FTP, what is the name for the five positions in space where a small object can remain stationary relative to two massive objects, named for an Italian-French astronomer and mathematician who developed the calculus of variations?
