The Leo is one of the most recognizable constellations in spring skies, although almost all of them are formed out of faint stars and have complicated shapes. A curve of stars arranged like a mark of "?" being turned over, "The Lion's sickle" that represents Leo's head. One of famous meteor streams, Gamma Leonids, has a radiant point in the sickle, and a violent meteor storm could be observed in November 2001.
Alpha Leonis is named "Regulus" meaning of the little king, the star was well known in antiquity as Cor Leonis, the Lion's Heart.
